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.

The Bengal cat is a considerably older breed than the others in this list, but as a breed derived from a wild cat hybrid, it is worth a look. The Bengal breed, which developed from a cross between a domestic cat and an Asian leopard Cat, is also the starting point for other breeds in this list. There have been stories of naturally occurring crossbreeds in Asia from way back, with the oldest confirmed case in 1934. The breed as we know it began with geneticist Jean Sugden-Mills, who crossed ALCs with domestic cats in 1963. Twenty years of breeding resulted in the breed that was accepted as truly domestic by TICA. Bengal cats are large cats with distinctive markings. Generations F4 and beyond are considered to be good house pets.
A loss of appetite and lethargy are both vague symptoms but the rapid breathing is concerning, you should visit your Veterinarian for an examination as rapid breathing may be associated with pain, anaemia, heart disease among many other conditions. Without examining Ozzy I cannot determine the specific underlying cause of the symptoms and would recommend that a visit to your Veterinarian be made before the weekend. Regards Dr Callum Turner DVM
Hi! This is my first time using this website. I adopted a kitten from the humane society two months ago. She is currently 6 months old. She is an extremely sweet and loving kitten and have had no problems with her except for some gum swelling around 5 mo. I took her to a vet and was told she was fine, the gum swelling went down and she lost some baby teeth. I assumed the gum swelling was from that. I am now noticing in her rapid breathing when she is resting, and more recently, at random times she makes a monotone short snore sound. It’s almost as if she is having issues breathing. I have noticed zero behavioral changes. She seems to be doing fine, however I know cats can hide their issues well. I will add she is a Siamese kitten and talks like one!
This semi-long-haired feline is native to Norway, according to the Cat Fancier’s Association, and everything it does, it does when it’s good and ready.  (You got that?) They’re described as sensitive, social and friendly but on their own terms. Despite their outdoorsy name, they’re quite happy inside but do require a scratching post and cat tree — preferably with an outdoor view — to keep them stimulated.
Thank you for your email. Since Tortie was just seen by your veterinarian and was deemed healthy, her periodic bouts of rapid breathing may be normal, and may follow bouts of exertion or anxiety. If the periods that she is breathing rapidly become more frequent, or more severe, it would be a good idea to have her seen by your veterinarian and examined to make sure that she is okay. It might be helpful to video the episode, since she doesn't seem to breathe that way when she is at an appointment. I hope that she is okay!
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.

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.


Not much is known about this rare breed; however, it is believed that the Russian blue originates from northern Russia, specifically the Archangel Isles. According to the Cat Fanciers' Association (CFA), cat rumor has it 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." As early as the sixteenth century, recorded history shows that trade ships passed between this territory and the British Isles, and the Vikings were active in both regions centuries prior, but there is no mention of the Russian blue cat until the nineteenth century.
My cat is recovering from having a tumor taken off of his neck. He is not thriving and today i found that he has blood in his urine. He is also breathing in short bursts. The doc said unless he seems very uncomfortable, it can wait till tomorrow, MOnday. I want the cat to see his usual vet, instead of taking him to emergency. What would you do? I don’t want him to suffer, so i gave him some pain meds.
Map out a regular routine for when you can do all of these things on a constant basis. Remember that the Russian Blue loves a good routine and will much more likely accept the treatment. Don’t forget to include playtime and petting to keep them happy. Your cat shouldn’t give you any problems during the grooming routine because they love to be combed, brushed and petted. In fact, the more time you spend with a Foreign Blue, the better!
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.
Allergy medicine wouldn’t help here, it may be a case that the beef tendon is causing pain or an obstruction for Kingston which may explain his posture of sitting and his increased respiratory rate. I would keep an eye on him, but if there is no improvement within a few hours I would recommend taking him into your Veterinarian for an examination; I wouldn’t induce vomiting since if there is an obstruction this may cause more pain and distress for him.

You’ll be immediately drawn to the Russian Blue’s shining green eyes and the silver-like, smooth coat. While majority of the coat is colored bright blue, the foot may sometimes have a lavender base that darkens as it travels upwards to the guard hair tips, which is the cat’s protective topcoat. The ends of each strand of fur sparkles with silver, often resembling the tips of spears when the light catches it.
Hybrids have always been popular. They make people feel connected with the wilderness outside. We can’t all own lions and tigers (nor should we), but so many people want little felines that resemble their larger, exotic cousins. Some breeders have begun breeding smaller wild species with domestic cats to create beautiful hybrids that are safe for the average cat owner to live with. Although hybrids are still controversial, there is no denying how unique and beautiful they are. Take a look at the most popular hybrids below.

The goal of breeding the Serengeti Cat is to produce a cat that resembles the wild Serval but does not contain any Serval bloodline. The first Serengeti Cat was bred by Karen Sausman in 1994 by crossing a Bengal and an Oriental Shorthair. This "foundation cat" and its progeny have been bred with many other types of cats to improve the breed—but no Servals. However, its lineage does include the Asian Leopard Cat whose genes contributed to its Bengal Cat ancestor. Serengeti Cats have long ears and long legs like a Serval, and a neck that does not taper where it meets the head. They are agile, active, and vocal. TICA classifies this cat as an advanced new breed.


Russian Blues like their daily routine to be just so, and dislike household changes more than the average cat— and the average cat dislikes household changes a lot. They particularly dislike changes to their dinner schedule, and will make you aware of their displeasure. They are also fastidious about their litter boxes and will complain or may even go elsewhere if they’re not spic and span.
A British cat fancier named Mrs. Carew-Cox began importing the cats in 1890 and bred and showed them through the turn of the century. She described them as having short, silvery fur, large ears, wide-set eyes and lean faces, with sweet, intelligent personalities—in short, much the same as the Russian Blue of today. In 1912, the cats were well enough established that they could be shown in a class of their own instead of being lumped together with other blue cats.
Any breathing difficulty should be seen by a Veterinarian regardless of cost since I cannot narrow in on a specific cause without examining Emilee thoroughly; there are many possible causes from airway inflammation, foreign objects to respiratory tract infections (among other causes). You should place Emilee in the bathroom with you whilst you shower in case there is mucus which may be loosened; but a visit to a Veterinarian, charity clinic or other organisation would be best.

A kitten turned up in my family's yard. Because of her tanish-grey coloring and the black tufts on her ears, we at first wondered if she was a bobcat kitten. A quick look at bobcat traits (she has a long black tail, no ruff of fur around her face) proved that not to be true, and we figured she was just a slightly odd-looking stray domestic cat. We took her in.


The Russian Blue can spend hours amusing itself and does not mind an awful lot if it is left at home alone for the day, but it will be very happy to see you when you do arrive. This cat makes for an excellent companion, constantly following its owners about, and generally preferring one human above all others in the family. It should be added that the Russian Blue gets along with most everyone, including children. Their love of human company extends to impishly clowning to help calm a crying baby, and showing sympathy when their people get the blues by patting the face of the person.

Two days is still early days for treatment but you should start seeing some improvement in the next day or so, I would say to give it the weekend and if there is no improvement in Jinx’s condition you should return to your Veterinarian on Monday for another examination. Improvement in an animal's condition, especially with antibiotics, can be delayed in most cases so unless your Veterinarian said specifically ‘you’ll see improvement over the next 24 hours’ or something similar you should give it three or four days at least.

What's wrong with my poor gravy? My cat Gravy has become extremely affectionate today and has followed me outside 3x, where he never ever goes! He's following me like a shadow and meowing at me more than normal. He doesn't seem to be in any pain, but his breathing and change of demeanor have me concerned. He's breathing fairly rapidly thru his nose, and he is moving his tail a lot also acting maybe as if he is worried?
