Sounds like extra fluid. My feline leukemia positive cat was belly breathing about 50 times a minute. I rushed him to the vet who said he had a hemo thorax and removed 200ml frothy blood. He had a tumor that was leaking and compressing lungs. He layed stretched out or up on his elbows. If your cat is belly breathing and breathing upwards of >30 minute-run to the vet! Sadly I put my baby to sleep that day. I had another cat with CHF (congestive heart failure) was treatable with meds. SHe lived a year.
It's no surprise that such a stately cat has such royal roots, with its sleek, sophisticated demeanor. Although it was exhibited alongside other blue cats, by 1912, the Russian blue was given its own classification, points out Vetstreet, after its introduction to the United States in the early 1900s. However, says the CFA, the breed really took ahold of pet lovers' hearts after World War II, and it has been gaining popularity steadily since the 1960s.
Feeding tamed big cats raw fish, raw porkchops, raw beef or raw rabbit together in an enclosed space will activate love mode. They can either be fed the meat, or it can be dropped next to them. After being fed and paired together, love hearts will show around the breeding pair, and after around 5–10 minutes, a cub will be produced and the naming screen will appear.
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!
Queening is a painful process just like childbirth is for humans and some heavy breathing or panting may occur afterwards for a few days due to discomfort. But if you feel that she is straining or in distress you should visit your Veterinarian to check her over to ensure that there isn’t a retained kitten or another issue leading to these symptoms.
