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.

This cat breed has a very interesting history. Sometimes referred to as Archangel Blues, the cats are believed to have originated in the Archangel Isles, located in Northern Russia, and may have been pets of Russian czars long time past. They’re considered a natural breed and not sprung from interbreeding programmes. The thick, warm coat is due to the cat needing something to keep warm against the frozen tundras and the cold, harsh winters of the country.


My kitten Rupert is only 7 weeks old and he started breathing rapidly the night before. At times he groans and breathes with his mouth open. He feels and sounds most uncomfortable when he is being held, but still has discomfort if laying down for a long time. I'm not sure if he has a cold, or if its something wrong with his lungs? He had just been in the emergency just 2 days ago for low blood sugar, but he wasn't doing this at that time. What do I do?

In one bit of Russian Blue lore, it’s said that the breed is a descendant of the royal felines kept by the Russian tsars. Contrary to that fun splash of folklore is the rumor that the Russian Blue cat actually originated on Northern Russia’s Archangel Isles (giving the breed the nickname Archangel Cat), where the breed was picked up by sailors in the 1800s and brought to Europe. And according to folklore, the Russian Blue is said to bring not just good luck but healing abilities, too!
It’s a well-known fact that Foreign Blues are hearty eaters. This cat breed will devour what you put in front of them and ask for seconds! If left alone, the sleek Russian Blue will turn fat and the target of weight-related conditions in no time. You can counter this dilemma by giving food only on specific periods and telling family members not to spoil the cat too much.

Actually what you are seeing are the different color phases of a Bobcat. During the winter months, they are brown or brown grey. That is why Boris looks grey in the center picture, that was taken during the winter. All 3 are now orange or a brown/orange mix. Nakoma has the most orange on him as does Amber. Boris, since he is still a kitten, just a little over a year old, he still has a combination of orange and brown. Next summer he will be more orange.
Although an immediate improvement in the bloodline was made when Russian Blues were imported from Britain, it would take years to establish the exact type that would personify the Russian Blue. Breeders were breeding traits into their lines based on their own preferences, so that their Blues would be splendid in one area, but never overall. The breed was too varied, with some exhibiting pale, exquisitely plush coats, and others showing elegant bodies, beautifully shaped heads, and striking green eyes.
The Russian Blue is not believed to be related to the other three shorthaired solid blue breeds: Thailand’s Korat, France’s Chartreux, and Britain’s British Blue (now called the British Shorthair). The four breeds have distinct differences in coat type, conformation, and personality, although the Korat, Chartreux, and Russian Blue share a similar silver-blue sheen. Since all four of these breeds have been around for so long that their ancestries are shrouded in legend and conjecture, a common ancestor is possible.
There are many different causes for an increase in respiration rate which may include pain, respiratory tract infection, parasites, tumours, anaemia, heart disease, pulmonary edema, poisoning, allergies among other causes; without examining Petey and diving into the case I cannot think of a specific cause. If the faeces are greasy I would look at changing the food to another brand and stick with a kibble over a wet food and look for any improvement. Regards Dr Callum Turner DVM
Some cats may breathe faster than others due to temperature, weight, allergies, pain among other factors; without examining Chip and doing x-rays etc… we cannot rule everything out. If you still have concerns, speak with your Veterinarian about having an x-ray done for peace of mind but if your Veterinarian has auscultated the chest and there are no concerning sounds you should just keep a close eye. Regards Dr Callum Turner DVM
Pulmonary thromboembolism (PTE) is a blockage in the pulmonary artery or one of its branches in the lungs that is caused by an embolism, a substance which has travelled through the circulatory system from another part of the body. The most common cause of pulmonary thromboembolism is a blood clot other causes include heartworm and a globule of fat. Blood can clot as a result of increased clotting disorders, heart disease, tumours, heartworm, polycythemia (increased red blood cells), and damage to the blood vessel walls.
A normal cat should always breathe with small movements of its chest. If your cat's sides are moving a large amount, this can indicate labored breathing. Unlike dogs, cats should generally never pant. You can also try to watch for any increased abdominal movements with your pet's breathing. If you cat is breathing normally, you shouldn't see any excessive movement in the abdomen, or any hitch to the breathing.

He purrs all the time and loves to play. His lips and nose are a nice pink as well as his tongue. His inner eyelids are fine. His eyes are only wide when he's ready to play. When he sleeps in a certain position, his heart rate is higher than normal, but when he sleeps in a different position, he breathes fast, over 40 breaths per minute. When I feel his heart, it's always beating fast but that's because he is very active and loves to play. When he sleeps in a different position, usually curled up, his breathing and heart rate are fine. Usually the rapid breathing is when his head is back, but he quickly wakes up to change position to become more comfortable. He normally plays for an hour or so, becomes tired, then goes to sleep.
According to a report in a 1978 edition of the British tabloid paper “Sun”, a “pantig” (panther-tiger hybrid) was born at Southam Zoo, a private zoo located on Warwickshire farm (Southam is between Royal Leamington Spa and Daventry). The purported pantig was the result of a mating between a male black leopard and a tigress and was fostered by a Dachshund. The cub’s background colour was the typical yellow-brown shade of normal leopards. Unlike earlier attempts at captive-breeding leopard-tiger hybrids, this purported hybrid evidently survived into adulthood. Eventually, the Southam Zoo pantig was sold to an American zoo. Although this account is currently not scientifically authenticated, it indicates that the leopard’s recessive melanism gene is also recessive to the tiger’s normal tawny color.
These cats have some serious staying power. Hailing from Siberia, this breed was first referenced all the way back in 1000 A.D., according to TICA. Powerful, intelligent and entertaining best describe the Siberian, which frequently takes problem-solving (like opening doors) into their own paws. Their semi-long coat is thick in the winter to withstand the elements and becomes shorter and lighter in the warmer months.
Adding to the captivating physical qualities of this breed is the eye color. The eyes are yellow while the Russian Blue is a kitten, and by four months there is a bright green ring around the pupil. As the cat matures, the eye color graduates into a bright, vivid green, aesthetically intensifying the already remarkable blue-silver coloring of the cat. The eyes are wide set and round, and only slightly slanted at the upper corners, giving the Russian Blue a sweet expression that matches well with its gentle temperament.
