Inconsistency in breed classification and naming among registries means that an individual animal may be considered different breeds by different registries (though not necessarily eligible for registry in them all, depending on its exact ancestry). For example, the TICA's Himalayan is considered a colorpoint variety of the Persian by the CFA, while the Javanese (or Colorpoint Longhair) is a color variation of the Balinese in the TICA and the CFA; both breeds are merged (along with the Colorpoint Shorthair) into a single "mega-breed", the Colourpoint, in the World Cat Federation (WCF), who have repurposed the name "Javanese" for the Oriental Longhair. Also, "Colo[u]rpoint Longhair" refers to multiple different breeds in some other registries. There are several examples of nomenclatural confusion of this sort. Furthermore, many geographical and cultural names for cat breeds are fanciful selections made by Western breeders to be "exotic"-sounding and bear no relationship to the actual origin of the breeds;[4] the Balinese, Javanese, and Himalayan are all examples of this trend.
Calico: Separate solid blocks of color, which must include red (orange), black, and white. They also may have blocks of tabby pattern, which produces an extremely colorful and beautiful cat. Dilute calicos, have the same separate blocks of color, only the colors are "diluted," i.e. "faded" shades of the original, which gives them an ethereal appearance. A dilute calico will have pale orange or buff for the red, and gray (or "blue") for the black.

In 1912 the Foreign Blue, one of the breed’s early names, warranted their own class and finally got separated from the blue cats variety. Progress of the cat’s popularity was halted, with the breed coming dangerously close to extinction during the onset of World War II. Breeders tried to revive the line by crossing the Russian Blue to Bluepoint Siamese and British Blues. Scandinavian breeders tried the same using Finland blue cats and Siamese blues.
World War II nearly put an end to the breed. Very few cats survived the years of privation, and British and Scandinavian breeders turned to other breeds, primarily the Siamese and the British Blue, to help revive their bloodlines. Because of the Siamese influence, the cats developed a more extreme look, and the texture of their coat changed. It took years to bring the breed back to its original appearance. That was achieved by combining British bloodlines, which emphasized plush, silvery coats, and Scandinavian bloodlines, which were known for producing cats with bright breen eyes and flat profiles. The result was the Russian Blue of moderate type seen today.
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.
Last, but maybe most important is, if you can pay to see wild cats on your terms (ie: cheaply, in a cage, or being forced to let you touch them and have your photo with them or their young) then you aren’t learning anything about who these animals really are. You aren’t learning about how they fit into a complex environment when they are housed in a situation that does not duplicate all of the web of life that they are a part of in the wild. All wild cats roam territories that are calculated in miles, not square feet. To know anything about them, you have to see who they are in their real environment.

Breathing rates may change for a variety of reasons and in some sleeping positions the airway may be slightly occluded which may result in altered breathing but without examining Kiki I cannot say for certain whether it is something to be concerned about or not. As for drinking, some cats may drink less that are on a wet food diet but you should ensure that she is keeping hydrated; you should visit your Veterinarian for a general check about the breathing and they can also check the hydration too.

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
Historians and cat lovers in Scandinavia and England worked tirelessly to map out a bloodline foundation for the cat breed. Records show that the first Archangel Blue appeared in 1875 to compete against similar blue breeds at the London Crystal Palace. One newspaper said that the Archangel was “particularly furry”, “very handsome” and “has similarities to that of the wild grey rabbit”. Before long, word was spreading around about the Russian Blue.

The first hybrids of the jungle cat (Felis chaus) and the domestic cat (Felis silvestris catus) may have been born in Egypt several thousand years ago.[2] The jungle cat is native to a vast region spanning Southeast Asia, India, and the Middle East (Sunquist, 2002). For the most part, it is an Asian species of wild cat that lives by rivers and lakes. But the species is found in one small area of North Africa: the Nile Delta. It is well known that the ancient Egyptians kept domestic cats as pets. Many domestic cat mummies have been found interred in Egyptian temples. What is not so well known is that one other species of cat was occasionally preserved after death via mummification; that was the jungle cat (Malek, 1993). F. chaus is not a timid species; they are known for moving into abandoned buildings and living as happily by irrigation canals as by wild rivers, provided that adequate prey and shrubbery for cover are available. Because domestic cats are likely to have frequently encountered jungle cats along the Nile and occasionally even within their owners' homes, it seems that hybrids of the two species were probably often born there.[3][better source needed]
It’s a great thing you went to the vet immediately. And even better news if the doc said everything seemed normal! We are no veterinarians – Paul and I – so please take your vet’s advice first. I would just add that it’s a good sign there’s not really other symptoms to the fast breathing other than loss of appetite (which might come back, or might already have since this morning??) It could be a small respiratory infection or a general feeling of unwellness, but your cat is older so it’s a good thing you checked with a vet first. Now it’s roughly 7:30 pm for you, I’d say if your cat is not having any other physical signs of distress or panting, blue gums, or anything bizarre, it will be safe to wait until the morning to see if the breathing has calmed. But please go with your gut and your knowledge of your cat!! If your cat’s behavior is still abnormal and he is refusing food then give another shot at the vet’s office. Possible bloodwork could be done and tests to see if there’s heartworm or other diseases that could be a cause for the prolonged, rapid breathing.
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.
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.
Without examining Kujo it is difficult to say specifically what the cause for panting is; sometimes there may be side effects from vaccines and other treatments but are self limiting and resolve themselves pretty quickly without veterinary intervention. However, if Kujo is struggling to breathe or there is no improvement you should return to your Veterinarian to be on the safe side. Regards Dr Callum Turner DVM
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!
