A supposed wildcat hybrid Bobcat (white) x domestic cat, with a further mating with a Highland Lynx to produce the curled ears. However, this is a selectively bred, totally domestic cat (no wild cat blood) that is meant to look like a bobcat. The Alpine lynx has longer hind legs and a large but not round head. The toes are tufted. They are intelligent cats.
About a month ago my 8 month old cat started panting after playing. I have also noticed for some time that her breathing is quite rapid even when sleeping. I called the vet and he suggested I take her for a check up. Everything seemed fine when the vet visited her but to be sure he told me to take her for a chest x-ray and blood test. I got the results yesterday and still no cause has been found to explain her breathing. All the tests were normal. The vet says he cannot rule out a heart problem and he suggests taking her to a cardiologist for a heart ultrasound. Apart from the panting (which is not every time she exercises but just occasionally) and rapid breathing (which I see every day) she seems a very health and active cat. I am not sure how concerned I should be about this. Perhaps it is just due to the heat. But I would not want to overlook a more serious underlying cause. I would not want to put her through any more distress by taking her a long way to a cardiologist. I would be grateful for any advice.
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.
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

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.
Give your Foreign Blue an adequate diet in the form of premium, dry cat food. You can spoil your cat from time to time and give him canned food that’s rich in protein. As they get older, dietary requirements may change, so it’s best to consult with a veterinarian for recommendations. When it’s time to change food, remember to add the new food gradually and mix it in the old one in the span of a few weeks or so. Make the transition too fast and your cat may get an upset tummy.
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.

Though I here you. There are those who have a special relationship with exotic animals, and they don't breed. I have feral cats, I trap, neuter and release. It takes a lot of patience as well as knowledge to have and care for an exotic animal, but it can be done. This is my friend and Nicky https://www.facebook.com/photo.php?fbid=472498366114433&set=a.453487321348871.109921.453002251397378&type=1&relevant_count=1.
My cat, Halia, is breathing heavily. However, she has mammary tumours which had reoccurred after prior removal of earlier tumours. On her second visit for the new tumours, it was found that the growth has spread to her lungs. The vets told me that any course of treatment at this stage will not be advisable or productive given that her tumours returned after only 2 months, and they are spreading very aggressively.
There are various different causes for rapid breathing which may include infections, pain, heart disorders, dehydration among other causes; a cat’s respiration should be below 30 breaths per minute when at rest but if it is significantly above this rate at rest I would suggest visiting your Veterinarian for an examination to determine a cause.
