Pneumonia is an infectious/inflammatory disorder of the lung parenchyma. Tiny bronchi fill the lungs; each one ends in smaller sacs known as alveoli which contain tiny blood vessels. Oxygen is added to the blood and carbon dioxide removed via the alveoli. Pneumonia causes these alveoli to fill with pus and fluids which affect the lung’s ability to exchange gases. There are several causes including infection (viral, fungal, bacterial, parasitic), aspiration of gastric contents or medications.
Cat fanciers may think that Russian Blues only have blue coating, but this isn’t always the case. In other cat associations such as New Zealand and Australia, the term “Russians” can be applied to black and white varieties, alongside the traditional blues. Even the U.S. Cat Fanciers Association and TICA allows black-colored Russians or Russian Whites into play in provisional cases.
Class clown — there’s always one! Purina notes that these confident and friendly creatures stand out because of their clowning around. These short-tailed cats, who were bred in the U.S. starting in the 1960s, according to TICA, make a great family pet since they’re sociable with humans of all ages and even other friends of the four-legged variety. They’re all about fun — but aren’t in need of your undivided attention — and don’t tend to attach themselves to one person.  
There are various reasons for an increased respiration rate and without examining Muffin it is difficult to narrow in on a specific cause; infections, pain stimulus, heart conditions, anaemia, poisoning among many other conditions may lead to an increased respiratory rate. If Muffin has a resting respiratory rate of 50 breaths per minute (shouldn’t be above 30 or 35) you should visit your Veterinarian for an examination to determine the underlying cause.

Solid black Chausies may have faint tabby markings (called ghost markings) as kittens, but usually acquire a dense, even black pigmentation with maturity.[8] Sometimes black grizzled tabby Chausies will appear indistinguishable from solid black Chausies when the amount of grizzling is minimal. Exposure to strong sunlight, as with most black cats, can cause black Chausies to lighten slightly and appear brownish.
The Maine Coon, one of the oldest in North America, was first discovered in Maine, where it is the official state feline. According to the International Cat Association (TICA), they are known and liked for their intelligence, friendliness and good-natured goofiness. (Fetch? Heck yeah!) They prefer to hang with their people versus being coddled by them.
My fiance said the he saw her eat this afternoon, so that is a relief. Her gums are pink (that's one of the first things I looked at on her and I should've told you that...but... this is my BABY CAT and she has me a little panicked!.. not like dealing with humans on the ambulance... she's innocent!) I do have access to oxygen... so we can make her an oxygen tent if it's necessary. Right now, she is getting up every couple of minutes and repositioning or pacing.. her respiration rate is around 50 right now... her belly almost looks like it's spasming and her heart rate is running between 80 and 90 everytime we take it... which is low... what do you suggest??????
