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.

Temperament: The Russian Blue is a distinguished, reserved, sweet cat. They make wonderful, loving companions but they may be reluctant to be social with people other than their family. They will bond with you and become fiercely loyal. Often, Russian Blues want to be right where you are, at all times. They will follow you around, helping you with whatever tasks you need to do and will happily snuggle up when it is time to rest. They do enjoy games and particularly love to teach their human counterparts how to fetch. They are playful and get along well with children who are gentle and treat them with respect. They are great pets and wonderful companions for families and will quickly wiggle their way into everyone's hearts.
Lots of places claim to be breeding cats to save them from extinction when in fact they are not involved in any real conservation effort and rather are justifying their breeding to have babies who will bring in paying visitors and worse yet to sell.  Many people contact us each week saying they want to start a captive breeding program to save the cats from extinction, but the only viable programs currently being operated in such a manner as to accommodate this goal are being run by accredited zoos who will not work with the private sector.  Unless you can trace your cat’s pedigree all the way back to the wild and you have been accepted into the Species Survival Plan for that specific breed, you will not be aiding conservation, but rather will be contributing to the over abundance of unwanted animals.
Stress may be a contributing factor for why Leo is breathing rapidly and sleeping, also a new environment may have other allergens or contaminants like cigarette smoke or different cleaning products which may cause some respiratory irritation. You should keep an eye on Leo for the meantime and if the problem continues you should visit your Veterinarian when you get back. Regards Dr Callum Turner DVM
When choosing your Russian Blue you should look for a reputable breeder, who will undoubtedly have a series of questions for you designed to make sure that you and the Russian Blue are compatible. Do not be surprised if there is a wait of some sort. These wonderful family members are worth it. Usually breeders make kittens available between twelve and sixteen weeks of age when they have had sufficient time with their mother and littermates to be well socialized and old enough to have been fully vaccinated. Keeping your Russian Blue indoors, neutering or spaying, and providing acceptable surfaces (scratching posts) for the natural behavior of scratching are essential elements for maintaining a healthy, long, and joyful life. For more information, please contact the Breed Council Secretary for this breed.
Lulu may be displaying perfectly normal behavior for an increase in temperature, or she may be having a problem. Without examining her, I have a hard time commenting on whether she is okay, but if she is acting normally otherwise, you may be fine to monitor her. If she continues to have rapid shallow breathing or seems to have problems catching her breath, it would be best to have her examined by a veterinarian.
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.

If Chester’s respiratory rate is over 100 breaths per minute you should visit your Veterinarian immediate for an examination since this is well over physiological range; infections, anaemia, allergies, congenital anomalies, foreign objects, fluid, parasites among other causes may be the underlying cause. I cannot give you any at home advice in a case this severe except to visit a Veterinarian for a thorough examination. Regards Dr Callum Turner DVM
Also known as dirofilariasis, heartworm disease (HW) is a serious parasitic infection caused by the nematode Dirofilaria immitis which lives in the pulmonary arteries, lungs, and hearts of cats. Heartworms are a type of roundworm, with adult heartworms reaching a length of 12 to 30 cm. Microfilaria (baby heartworms) are present in the blood of an infected animal (in most cases, a dog), when a female mosquito feeds on the blood, microfilaria are also ingested, once, inside the gut of the mosquito, they undergo further development before migrating to the labium (a part of the mouth) of the mosquito. When the infected mosquito feeds on another host (in this case, your cat), the larvae move from the mouthpart and onto the skin of the cat (or dog), from there, they enter the bloodstream via the bite wound left behind by the mosquito.
One of the Blue Russian's vulnerabilities is its tendency to be startled easily. They also have a natural proclivity to shyness and nervousness around strangers and in strange environments. If it is true that this breed was once the target of fur hunters (as some say), this would easily account for their caution and quick footedness. They would have had to move fast at the slightest sound to quite literally preserve their own skins.
Savannah cats are created by crossing a house cat with an African Serval. The original hybrid is called an F1 and is considered too "wild" to be a house cat. When you breed an F1 Savannah with another Savannah or another cat breed, the resulting kittens are called F2. Breeding F2 females produces a generation called F3, which still has a considerable amount of Serval genes, but three generations of domesticity. F1 females are retained as breeding stock, although the male hybrids are often infertile. Sometimes F2 or F1 Savannahs are bred with Servals to create Savannahs with a higher number of Serval genes. Or they may be bred with Savannah males of even later generations (F5 or F6). Male Savannahs are usually sterile in the first few generations.

The Russian blue is a sweet-tempered, loyal cat who will follow her owner everywhere, so don't be surprised if she greets you at the front door! While she has a tendency to attach to one pet parent in particular, she demonstrates affection with her whole family and demands it in return. It's said that Russian blues train their owners rather than the owners training them, a legend that's been proven true time and again.
