Cats can also develop fluid build up in the chest that is localized outside the lungs. This happens in an area named the pleural space. When fluid accumulates in the pleural space, the lungs cannot inflate as much as they should. Your cat will develop shortness of breath and labored breathing as more fluid fills this space. According to VCA Animal Hospitals, some causes of pleural effusion include:

The domestic short-haired and domestic long-haired cat types are not breeds, but terms used (with various spellings) in the cat fancy to describe mongrel cats of a general type, by coat length, that do not belong to a particular breed. Some registries permit them to be pedigreed and they have been used as foundation stock in the establishment of some breeds. They should not be confused with standardized breeds with similar names, such as British Shorthair and Oriental Longhair.

During this same time, Scandinavian breeders crossed similar looking blue coated cats from Finland with Siamese cats. The cats had emerald green eyes. Russian Blues made their way to North America in the early 1900s but it took some time for breeding programs to begin in North America. The first Russian Blue was not registered with the CFA until 1949. In 1964, GC Maja Acre Igor II, a Russian Blue, won CFA Grand Champion. In 1965, British breeders began to express concern over the evolving appearance of the Russian Blue cat breed. Russian Blues were bred with the similar looking Scandinavian cats that had beautiful emerald eyes and the Russian Blue look and personality that was desired was finally achieved.


This is about my cat. He was fine when he was a kitten other than being feral and not used to people. But about two months ago, he started doing this thing where he is breathing fine and all one minute and the next it sounds like his breath is coming out in quick bursts almost like coughing. And it always goes for about 8 or so bursts of breath. Is this something I should take him to the vet about ?
If your cat is having difficulty breathing, this can be a life threatening emergency. It is important to have your cat seen by a veterinarian as soon as possible. You will need to give a thorough history of your cat's health, onset of symptoms, and possible incidents that might have preceded this condition. During the examination, the veterinarian will carefully observe how your cat breathes, and will listen to its chest for evidence of a heart murmur or fluid in the lungs. Your cat's gum color will be carefully evaluated as well, since the color of the gums can indicate whether oxygen is being delivered to the organs (hypoxemia) effectively, or if it there is a low red blood cell count (anemia). Your veterinarian may try to get your cat to cough by pressing on its windpipe. If your cat is having extreme difficulty breathing, the veterinarian will give your cat oxygen to help it breathe before doing any more tests.
Pulmonary thromboembolism (PTE) is a blockage in the pulmonary artery or one of its branches in the lungs that is caused by an embolism, a substance which has travelled through the circulatory system from another part of the body. The most common cause of pulmonary thromboembolism is a blood clot other causes include heartworm and a globule of fat. Blood can clot as a result of increased clotting disorders, heart disease, tumours, heartworm, polycythemia (increased red blood cells), and damage to the blood vessel walls.
Pleural effusion is an abnormal buildup of fluid up in the pleural cavity, the thin fluid-filled space that lies between the lungs and the chest wall. It is a symptom, with an underlying disorder causing this fluid to build up. The buildup of excess fluid leads to difficulty breathing, due to the inability of the lungs to fully expand. Causes include congestive heart failure, liver failure, fluid overload, blood clotting disorders (usually due to ingestion of rat poison), lung lobe torsion, pulmonary edema, and diaphragmatic hernia.
It's no surprise that such a stately cat has such royal roots, with its sleek, sophisticated demeanor. Although it was exhibited alongside other blue cats, by 1912, the Russian blue was given its own classification, points out Vetstreet, after its introduction to the United States in the early 1900s. However, says the CFA, the breed really took ahold of pet lovers' hearts after World War II, and it has been gaining popularity steadily since the 1960s.
^ "Colorpoint Longhair" has multiple meanings and "Javanese" has been used for at least one other breed; the WCF uses the "Javanese" name for the Oriental Longhair (not colorpointed). The WCF has also merged the colorpointed Javanese/Colorpoint Longhair, the Himalayan and the Colourpoint Shorthair of other registries into a single breed, the Colourpoint. In the CFA, the TICA and some other registries, the Javanese/Colorpoint Longhair has merged back into the Balinese as a division

I'm afraid that I can't offer much more assistance for Bella than what you have already done, without being able to see or examine her. If she has not had a trans-tracheal wash, that may be one test that can help determine the type of cells that are present in her lungs, and if the x-rays have not been evaluated by a specialist, that is another possibility, as your veterinarian should be able to send those x-rays to be evaluated further.
We receive requests every week from people who are looking for some place to take their “pet” cat.  Each year we have to turn away more than 100 such “pets“.  These unwitting owners have discovered that all exotic cats, both male and female, neutered or not, spray and bite when they reach sexual maturity.  (They don’t just spray a little either.  We are talking about buckets of the foulest smelling urine, all over your house, your things and you. If you don’t believe me, watch this clip of a neutered lion HERE)  Moving them out to the yard means your neighbors will soon be complaining that your place smells like a zoo.   By the time they find us they have discovered that the zoos do not want their animals, that no one is willing to buy them and that they can’t even give them away.  Refuges are usually full to capacity and cannot take in another hungry mouth to feed.  All too often, these “pets” are turned out to fend for themselves, where they surely die of starvation or are euthanized.

There are many causes for a cat to have heavy breathing and without examining Jagger and auscultating his chest etc… I cannot say if there is a cause for concern or not; however heavy breathing may be caused by stress, pain, infections, obstructions, heart conditions among other causes. You should keep an eye on Jagger and visit your Veterinarian if you have any concerns or symptoms get worse. Regards Dr Callum Turner DVM

Thank you for your email. Without examining Missy, I can't comment on what might be going on. She may just be a skittish cat, given all of the change that has gone on in her life recently. IF she is eating and drinking normally, and seems healthy otherwise, she may be okay. If she seems to be having breathing problems. it would be best to have her seen by your veterinarian, and they will be able to determine if she is normal, or has a problem. It is nice of you to help this cat when she needs it. I hope that she is okay.
Congestive heart failure is a life-threatening disorder which occurs when the heart doesn’t pump blood as efficiently as it should which causes fluid to back up in the lungs and abdomen, while other organs don’t receive enough blood to function properly. It can be caused by heart diseases such as cardiomyopathy, heartworm, myocarditis, endocarditis, congenital disorders, high blood pressure, tumours, hyperthyroidism and acromegaly.
It’s human nature to become a creature of habit. However, there’s no room for health practioners to be complacent or lack empathic best practices. Your vet (and even your own doctor) should readily give you a plan that prepares you for multiple scenarios with situational based set of instructions of what to look for and what to do if things change. That said, the patients also have the responsibility of participating in the process. This can include keeping them on point by being their supervisor, so-to-speak, during the visit and making sure they do everything they’re supposed to do.
This cat breed has a very interesting history. Sometimes referred to as Archangel Blues, the cats are believed to have originated in the Archangel Isles, located in Northern Russia, and may have been pets of Russian czars long time past. They’re considered a natural breed and not sprung from interbreeding programmes. The thick, warm coat is due to the cat needing something to keep warm against the frozen tundras and the cold, harsh winters of the country.
The Chausie was developed from hybrids of the Jungle Cat (Felis chaus), the largest species of the genus Felis, found in Asia. They can grow up to three feet long and weigh 35 pounds, but are generally around 18 pounds. Like the hybrids that developed into the Savannah and Bengal breeds, the males of the first few generations are usually infertile, and the F4 and F5 are considered truly domestic and suitable for cat shows. TICA classifies the Chausie as a championship breed.
Los Angeles cat breeder Judy Sugden has been working since the late eighties to breed a house cat that resembles a tiger. The result is the Toyger, a registered breed that has a lineage beginning with domestic shorthairs and Bengals selected for their markings. Toygers are now available from breeders all over the world. The breed is still in development, and TICA now has the toyger classified as a championship breed. 

Treatment for congestive heart failure is aimed at managing the medical cause of the condition as well as relieving symptoms associated with fluid build up in the lungs, pleural space, and abdomen. In a few situations, once the cause has been treated (such as hyperthyroidism), the heart may recover, however, most cases of CHF are irreversible, but it may be managed to slow down the progress. Stabilising your cat if he has fluid build up in the lungs or pleural cavity, relieving symptoms and this may include:


Little is known about the origin of the Russian Blue breed, though stories are legendary. Many believe the Russian Blue is a natural breed originating from the Archangel Isles in northern Russia, where the long winters developed a cat with a dense, plush coat. Rumors also abound that the Russian Blue breed descended from the cats kept by the Russian Czars. Assuming the Russian Blue did migrate from northern Russia, it was likely via ship to England and northern Europe in the mid 1860s.

Sadly Arwen got worse throughout the night. She started to seizure and her breathing got worse. Then she started to not be able to move or blink her right eye and her wyes completely dilated until you could no longer see the pretty green. Finally she started to get severe swelling under her tongue and had even a harder time breathing. I took her to a vet asap but it was too late and she had to be euthanized. My vet thinks she had a massive stroke and even if we could of gotten her there sooner the outcome would of been the same. I've never heard of a cat so young getting a stroke like that, is it that unusual and what could of caused that? She was abused in her previous home and I think that factored into her very nervous disposition, she was very sweet and loving but was scared of just about everything. I guess I'm just trying to find a reason why and how but I'm also still just so upset too.
In the late 1890s/early 1900s, two hybrids were born in Chicago, USA, followed 2 years later by three sets of twin cubs born at a zoo in Hamburg, Germany from a puma father and leopard mother. Carl Hagenbeck apparently bred several litters of puma x leopard hybrids in 1898 at the suggestion of a menagerie owner in Britain; this was possibly Lord Rothschild (as one of the hybrids is preserved in his museum) who may have heard of the two hybrid cubs bred in Chicago in 1896 and suggested Hagenbeck reproduced the pairing.
These intelligent animals will require substantial amounts of physical and mental activity. Keep toys lying around the house at all times. When they feel the need to “hunt”, a ball of string or a toy fish should capture their attention for hours. Keep in mind that these types of toys require human supervision as the contents could be chewed up, which can be harmful for your cat’s health.

When the Russian Blue cat sees his favorite family member, though, it’s a whole different matter. This cat will follow the individual around the whole house and can sometimes hitch a ride on that person’s shoulder. The Foreign Blue greets the owner at the door and is sensitive to your mood, i.e., with playtime or just by settling down next to you. Owners rarely hear the cat’s voice unless it’s mealtime. Some of the things an Archangel Blue appreciates are a hearty game of fetch, a window with a great outdoor view and pats on the head.

Hi Farhood, thanks for reaching out to us! Thanks for taking care of this little stray 🙂 If you say she doesn’t display any of the symptoms and is eating well, it wouldn’t seem like she has any underlying issue. That is pretty hot, so make sure she has an area nicely covered by shade (plants, garden, etc). She isn’t panting, is she? Panting shows signs of heat exhaustion. Here, please read our article on keeping cats cool in the summer. Hope it helps! Best of luck.
Rapid breathing (tachypnea) is a respiratory disorder characterised by abnormal breathing that is rapid and shallow.  It is caused by a reduced level of oxygen, mechanical disorders (where the lungs aren’t able to expand as they should, usually due to a build-up of fluid in or around the lungs), and physiological disorders in which the cat’s respiratory centre in the brain is over stimulated.
Chest x-rays and standard blood tests may be indicative of valley fever but the condition is only confirmed with a specific test for valley fever; all other indicators may say valley fever but we still need the test to confirm. However if Nunzi has any response to the antifungal treatment then it adds another tick in the box for valley fever.

Without examining Tilly I cannot say for certain whether I would recommend euthanasia or not; but if she is struggling to breathe, seems in pain and your Veterinarian hasn’t recommended any surgical options (due to age or location of tumour) then you may want to think about euthanasia. It is a very difficult decision to make, but you need to look at Tilly’s quality of life and what the future holds for her. Regards Dr Callum Turner DVM
Russian Blues have a tolerant nature toward children who treat them kindly and respectfully. They will even put up with the clumsy pats given by toddlers, as if they recognize that no harm is meant, and if necessary they will walk away or climb out of reach to escape being bonked on the head. That said, the patient and gentle Russian Blue should always be protected from rough treatment, so always supervise very young children when they want to pet the cat.
Russian blue cats are highly intelligent animals and require physical and mental stimulation, so it's important to give them access to toys at all times. They retain a strong hunting instinct, so a feathered fishing pole toy is the perfect plaything. Consider storing these types of toys in a cat-proof spot because: (a) your kitty will tear it to shreds, and (b) she may eat the feathers and/or the string, neither of which are good for her digestive system or overall health.
The CFA describes the Foreign Blue as “having a medium-sized, smooth wedge for a head with a muzzle that’s short and blunt.” The flatness of the head and its wedge-shaped appearance can be likened to that of a cobra. At the head protrudes wide ears having a pointed tip. The eyes are wide-set and has a bright green tint. Overall, the eyes give the Foreign Blue a sweet expression that perfectly matches the breed’s outstandingly gentle temperament.
Lion coloration is usually orange-brown, with the exception of white lions. The underparts are generally lighter and the tail tuft is black. One of the most distinctive features about lions is that male lions have a large mane, whereas lionesses lack manes. The way to tell the difference between a male and a lioness cub is by looking at their neck; male cubs have small black manes, however, it is more difficult to to tell the difference between a male and female white lion cub.
Don’t let the powerful, sleek features of the Foreign Blue fool you. This breed is generally shy, quiet and very gentle by nature. It’s more reserved than playful but that doesn’t mean the breed enjoys a good romp every now and then. The Russian Blue is intelligent and leans towards games that have a “throw and catch” mechanism. You’ll soon find yourself playing an endless game of fetch if you’re not careful! They are also attracted by sunbeams, laser pointers and love to go chase their favorite toys.
This breed does not like change, preferring for things to be uniform and predictable. It can be thrown off when dinnertime is altered, and is nit-picky about hygiene. It will not even enter its litter box if it is dirty. In the early years, this breed developed a reputation at shows for being difficult to work with because of traits like these. The Russian Blue was gentle and happy at home, but at shows it was visibly discontent and temperamental. Popularity declined and fewer Russian Blues were being shown until breeders focused on improving the attitudes of the breed through selective breeding and behavior management (e.g., soft music, recording of show noises, crystals, herbal remedies). This commitment to the breed paid off, and today the Russian Blue is a happy participant at cat shows.
