Although the official, permissible outcrosses for the Chausie breed are the Abyssinian and the domestic shorthair (no recognizable breed), in practice any kind of purely domestic outcross can be used. TICA rules only dictate that cats must be a certain number of generations removed from the jungle cat ancestors and have three generations of registered Chausie ancestors to be eligible for competition at shows.[1] Consequently, a variety of breeds, albeit usually lively outgoing breeds (see below), were used to develop the Chausie breed and continue to be used occasionally as outcrosses. This has given the breed a diverse and healthy genetic foundation.
Russian Blues are very intelligent. My female knows commands and obeys. If I say no she responds with a quiet meow but obeys. My male is the most affectionate cat I have ever had while my female decides when she is to be loved. She sits on my shoulder while I put on makeup and knows how to signal me to bend over so she can jump onto high places like the top of an armoire or top shelf of the closet. Love this breed and are very loyal and clean cats.
If the resting respiratory rate is above 40 breaths per minute, you should ideally visit a Veterinarian for an examination as it can be difficult to narrow in on a specific cause; there are a few possible causes for this rapid breathing including infections, laryngeal disorders, pain among other causes. You should visit a Veterinarian as soon as possible for an examination to narrow in on a cause. Regards Dr Callum Turner DVM
First exhibited at London’s Crystal Palace in 1875 as the “Archangel Cat,” the original Russian Blue competed with all other blue cats. In 1912, the Russian Blue was given a separate class for competition as breeders in England and Scandinavia worked to develop the foundation bloodlines for the contemporary Russian Blue. Although Russian Blues were imported to the United States in the early 1900s, it wasn’t until after World War II that North American breeders began combining the European bloodlines to produce cats with plush, silvery coats, emerald eyes, and the distinctive profile. From the 1960s, the Russian Blue began gaining popularity and has become a favorite at cat shows and at home.
My cat was originally a stray and when I found her she was in perfect healthy. We regularly took her to her check ups. She is tiny but she appears to be an American shorthair. But, as of recently she started breathing weirdly. She would lay on her stomach and this rattle sound would emit from her body. Her breathes would change from shallow and rapid to deep and slow. Before this happened, she had a slight cough with the same rattle noise. Like a human with an infection in their lungs. When we took her to the vet they would tell us she was fine. She was active and still regularly eating. We've taken her to multiple veterinary clinics and they've all told us they aren't sure what she has. They've done multiple Xrays and still cant seem to narrow the problem. We've put her on several antibiotics prescribed by the vet but nothing seems to make a dent. They offered the idea of asthma. We gave her treatment but still nothing. They told us it seemed that she had air pockets and some fluid. We ended up paying a ridiculous amount for treatment of a washout and still nothing. She eats regularly but her breathing is still the same. There was this one time she sneezed and big amount of mucus discharge came from her nose. No matter who we go to they all tell us we need to prescribe more expensive treatment just so they can say they don't know in the end. Can you help us?

The Russian Blue has a reputation as a gentle, quiet cat, somewhat shy, but don’t get the wrong idea. This cat may have a reserved nature, but he loves to play (being especially fond of retrieving) and enjoys jumping or climbing to high places where he can study people and situations at his leisure before making up his mind about whether he wants to get involved. Guests will not receive his immediate attention and may never see him unless he decides they are worthy of his notice, but toward family members, especially his favored person, he is ever loyal, following them through the house and even riding on a shoulder. The Russian Blue is a sensitive cat who doesn’t like to be ignored and will be hurt if he doesn’t receive the same amount of affection he gives. Lack of attention can cause him to become anxious or fearful.
My cat isn't eating his treats which is VERY unusual for him. He's sitting like he's uncomfortable or ready to dash. He's also making a very weird, low noise almost like an attempt at a growl or purr but it isn't quite there. I also noticed he is breathing rather quickly. The article I read here said 20-30 breaths a minute and it looks like he's doing 40 in 30 seconds. His gums don't look pale or blue. Just the normal pink. His nose is still cold too. I haven't seen blood anywhere on him or in his litter box. It also seems like he hasn't vomited at all either.

Kokwa may be breathing fast due to stress, pain, respiratory infection, heart conditions, anaemia (check gums), poisoning among other causes; without examining Kokwa and listening to the heart and lungs I cannot say specifically what may be wrong. You should keep a close eye on Kokwa and if the breathing doesn’t improve you should visit your Veterinarian in the morning or if you see he is in respiratory distress or his gums are white visit an Emergency Veterinarian immediately.

Origin: The exact country of origin is unknown but the Russian Blue first appeared in cat shows in London. Though, it is widely believed that the breed is most likely from Russia because their thick double coat suggests they had been well adapted to living in very cold climates. The common story is that British sailors fell in love with this breed of cat on their travels and brought them home from the White Sea port town of Archangel. In 1871, the blue coated cat first made its appearance in a cat show at the Crystal Palace in London.

It’s a good idea to keep a Russian Blue as an indoor-only cat to protect him from diseases spread by other cats, attacks by dogs or coyotes, and the other dangers that face cats who go outdoors, such as being hit by a car. Russian Blues who go outdoors also run the risk of being stolen by someone who would like to have such a beautiful cat without paying for it.
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.
Pulmonary edema is the buildup of fluid in the within these air sacs leading to shortness of breath. Located in the lungs are thousands of air sacs (alveoli) which are small balloon-like structures where the exchange of carbon dioxide and oxygen occurs. Tiny capillaries surround the alveoli on the outside. When the cat breathes in, air enters the lungs, causing the alveoli to expand. Oxygen passes from the alveoli and into the capillaries, carbon dioxide from the capillaries pass into the alveoli and is exhaled out. The most common causes of pulmonary edema relate to problems with the heart, such as hypertrophic cardiomyopathy.  Heart diseases can lead to reduced movement of blood through the capillaries in the lungs. As the blood flow slows, fluid leaks out of the vessels into the airways. [1]
Thank you for you email. unfortunately, without examining Kai, i can't comment on what might be going on with him. He needs to see his veterinarian to try and determine what is going on with him and how to treat him. If he seems to be in distress and unable to catch his breath, taking him to the emergency clinic tonight is most appropriate. I hope that he is okay.
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.
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.
Although the official, permissible outcrosses for the Chausie breed are the Abyssinian and the domestic shorthair (no recognizable breed), in practice any kind of purely domestic outcross can be used. TICA rules only dictate that cats must be a certain number of generations removed from the jungle cat ancestors and have three generations of registered Chausie ancestors to be eligible for competition at shows.[1] Consequently, a variety of breeds, albeit usually lively outgoing breeds (see below), were used to develop the Chausie breed and continue to be used occasionally as outcrosses. This has given the breed a diverse and healthy genetic foundation.
Four of the five species of the big cats (the Panthera genus – lion, tiger, leopard, jaguar and snow leopard), the exception being the snow leopard can hybridize with each other to produce numerous hybrids. In fact, breeding of two different pantheras to produce hybrid big cats has been banned in many zoos and animal sanctuaries due to no conservation value of the hybrid, and the risk it poses on the mother that gives birth to it.
Below are some zoos and pseudo sanctuaries in Florida.  These places breed and sell while lying to the public and saying they are doing it for conservation.  The file is large, so you may have to wait a bit for it to load fully and then hit play again. These are the ones that are open to the public. Many are much worse, but do not allow the public in to film.
Without examining Midnight it is difficult to give a diagnosis since lethargy and loss of appetite are vague symptoms common with many different conditions; infections, parasites (regardless of indoor or not), foreign objects, poisoning, spoiled food, injury (fell from somewhere) among many other causes may lead to these symptoms. You should ensure that Midnight is kept hydrated, but if there is no improvement you should visit your Veterinarian for an examination. Regards Dr Callum Turner DVM

Tri-color Cats: Because of the associated genetic factors that create their color patterns, tri-color cats almost always are female, although occasional males crop up (about one in 3,000, according to this excellent article by Barbara French) Those rare males are almost always sterile, also for reasons of genetics, so don't expect to gain a fortune by selling your male calico cat.
Adding to the captivating physical qualities of this breed is the eye color. The eyes are yellow while the Russian Blue is a kitten, and by four months there is a bright green ring around the pupil. As the cat matures, the eye color graduates into a bright, vivid green, aesthetically intensifying the already remarkable blue-silver coloring of the cat. The eyes are wide set and round, and only slightly slanted at the upper corners, giving the Russian Blue a sweet expression that matches well with its gentle temperament.
