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.

Watching the rate of breathing is one of the simple observations that you can make on a pet cat at home. This cat has a problem known as "tachypnoea", which means rapid breathing. IF you watch her side carefully, you'll notice that her sides are moving much more quickly than a normal cat at rest. Her problem is being investigated, so the precise cause is under review, but it's most likely that she has "hyperthyroidism", caused by a benign tumour on her thyroid gland
In 1871 a Russian Blue was shown at the first cat show at the Crystal Palace in London, under the name Archangel Cat. At this point, Russian Blues were shorthaired, solid blue felines with foreign body types. From photos and published sources of the time, the original coat was thick, dense, glossy, and colored a light silver-blue. Russian Blues competed in the same class with all other shorthaired blues, despite obvious differences in type. Since the round-headed, cobby British Blues were favored in the show halls, the slender Russian Blues rarely won.
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.
There are many different options for analgesia in cats, however without knowing which medication was provided for pain relief I cannot give you an indication of how long it would be effective for as we have many different products on the market with different active ingredients, mechanisms of action and duration. A respiratory rate above 35 or 40 breaths per minute is expected as a result of discomfort or pain, but without examining Chester or knowing what was administered I cannot give you any specific information.

Long term prognosis for recovery of your cat will vary from cause to cause. Infections and pneumonia are serious illnesses that need a high degree of specialized veterinary care. In all cases, your cat’s chances for a full recovery will increase if immediate veterinarian care is sought as soon as initial symptoms are detected. Additionally, given the seriousness of lung and breathing issues, you should follow up after symptoms in your cat have resolved in order to prevent potential recurrence.
As with so many cat breeds, little is known of the Russian Blue’s origins. He probably does come from Russia—his thick coat is surely that of a cat from colder climes—and he is considered a natural breed, meaning Matushka Nature created him, not the handiwork of humans. The Russian Blue’s development as a breed, however, took place primarily in Britain and Scandinavia, starting in the late nineteenth century, when showing and breeding cats became a popular activity.
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.
We receive requests every week from people who are looking for some place to take their “pet” cat. Each year we have to turn away more than 100 such “pets“. These unwitting owners have discovered that all exotic cats, both male and female, neutered or not, spray and bite when they reach sexual maturity. (They don’t just spray a little either. We are talking about buckets of the foulest smelling urine, all over your house, your things and you. If you don’t believe me, watch this clip of a neutered lion HERE) Moving them out to the yard means your neighbors will soon be complaining that your place smells like a zoo. By the time they find us they have discovered that the zoos do not want their animals, that no one is willing to buy them and that they can’t even give them away. Refuges are usually full to capacity and cannot take in another hungry mouth to feed. All too often, these “pets” are turned out to fend for themselves, where they surely die of starvation or are euthanized.
Little is known about the origin of the Russian Blue breed, though stories are legendary. Many believe the Russian Blue is a natural breed originating from the Archangel Isles in northern Russia, where the long winters developed a cat with a dense, plush coat. Rumors also abound 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.
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. 
Rapid breathing (tachypnea) is a respiratory disorder characterised by abnormal breathing that is rapid and shallow. It is caused by a reduced level of oxygen, mechanical disorders (where the lungs aren’t able to expand as they should, usually due to a build-up of fluid in or around the lungs), and physiological disorders in which the cat’s respiratory centre in the brain is over stimulated.
