Pyothorax (pleural empyema) is the presence of pus in the pleural space in the chest cavity, the thin, fluid-filled space that lies between the lungs and the chest wall. Any pathogenic organism can cause pyothorax including fungal, viral, bacterial or protozoal; however, a bacterial infection is by far the most common pathogen. The collection of pus is due to dead white blood cells and dead bacteria. Common bacteria involved in pyothorax include Pasteurella spp (the most common), Nocardia spp,  Streptococcus spp, Clostridium spp, Proteus spp, Bacteroides spp and Mycoplasma spp.


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.
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.

Breeding of Russian Blues took a lot of years and tweaking as many breeders had different preferences as to what exactly they thought the Russian Blue should be like. The breed became very varied and finally, North American breeders began to import Russian Blues from Britain and the breed began to stabilize. Russian Blues are known for their skittish, shy personalities and struggled to perform in cat shows. This problem led to a decline in popularity but breeders worked hard to carefully cultivate the desired personality and, since the 1990s, Russian Blues have done much better in cat shows and have become much more popular among fanciers.
The Russian Blue stands out for his coat color. To the uninformed, he might look gray, but in cat show terms he is an even, bright blue with silver-tipped hairs that make him seem to glisten. Some Russian Blue kittens are born with “ghost stripes,” a reminder of the tabby gene that all cats carry, even if it isn’t expressed in their coat, but these generally fade, leaving the cat with the solid blue coat of maturity.
Hello there! My girlfriend and I have an exclusively outdoor cat who has recently shown some worrisome behavior. Typically, Simba is very independent. Only allows some human interaction when we feed him, and even then it's more like we have to sneak a pet here and there. About three days ago I came home and noticed his breathing was fairly rapid. I thought maybe he just came to our porch after some activity, so I mentioned it to my girlfriend in passing. Yesterday she called me at work worried. Simba was letting her pet him and even came into our garage (which is basically set up like a living room. There's a heater, ac unit, tv, carpets, etc.) It's very home-y. Anyway, he's been in the garage the past two nights since its been in the thirties at night time. He lays very still, breathes very rapid and heavy. I can hear, what I think is congestion as he breathes. He hasn't eaten or drank much. The only thing I have gotten to eat are a few cat treats. I read online we could give him a small dosage of benedryl. But I don't want to give him anything that would essentially hurt him. He also has random asthma like episodes. Wheezing and coughing with his mouth closed. He meows when we talk to him, or look at him. Part of me feels like he's asking for help! Unsure if whatever he has is life threatening or just a little kitty cold.

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.

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.
Ligers enjoy swimming, which is a characteristic of tigers, and are very sociable like lions. Ligers (and tigons) exist only in captivity because the habitats of the parental species do not overlap in the wild. Historically, when the Asiatic Lion was prolific, the territories of lions and tigers did overlap and there are legends of ligers existing in the wild.
Cats, both pedigreed and domestic, come in a rainbow of colors and patterns. These are all a matter of genetics, so a calico mother might give birth in one litter to calico, tabby, and solid or bicolored kittens, depending on her genetic background and the background of the male cat(s) that fathered the litter. Cats, come in three basic colors (called "self" by geneticists): red (commonly called "orange," or sometimes affectionately referred to as "ginger," or "marmalade"), black, and white.
Your cat’s health is of the utmost importance, and at some point, most owners are faced with a confusing medical issue they must confront. Do cat’s normally breathe fast? Yes but only in very specific conditions. If you’ve found yourself looking at your furry friend and wondering “My cat is breathing fast – what should I do?” your next step is to make an informed decision of how to react to this respiratory difficulty.

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!
