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.
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.
Hmmm where did you get this information? I haven't heard of any Bobcat/Siamese crossing. Just because a cat has a bobbed tail, does not mean it was crossed with a Bobcat. When talking Bobcat, do you mean an American Bobtail, or a similar breed, or a true 100% Bobcat. There is a breed of cat that, as the legend goes, has been crossed with a wild Bobcat. The breed is known as the Pixie Bob. I have 4 Pixies and yes, they do have some traits that do resemble a Bobcat. Not just with their coloring and markings, but with their behaviors as well. Amber and Boris, pictured in my signature, are true wild Bobcats. The idea of crossing a Bobcat with any domestic cat is not as easy as some may think. For one, Bobcats are very aggressive breeders and have been known to kill each other while breeding in captivity. The thought of putting any domestic cat in with an intact male Bobcat is just asking for trouble. The legend of the Pixie Bob is that this breeding took place in the wild, with the crossing of a male Bobcat with a female domestic "barn cat". These male Bobcats may have been older males, who no longer could compete in the wild with much younger males. Whether or not this legend is true has not been proven. Yes, the look of the Pixie Bob does resemble a Bobcat to some degree. The Toyger cat, a new breed of domestic cat, has been bred to resemble a small tiger, the same size as most domestics. The coloring and markings are there, but there is now way that this cat was crossed with a tiger. These markings and coloring come about by selective breeding and take years to produce the final results the breeders are looking for.
The goal of breeding the Serengeti Cat is to produce a cat that resembles the wild Serval but does not contain any Serval bloodline. The first Serengeti Cat was bred by Karen Sausman in 1994 by crossing a Bengal and an Oriental Shorthair. This "foundation cat" and its progeny have been bred with many other types of cats to improve the breed—but no Servals. However, its lineage does include the Asian Leopard Cat whose genes contributed to its Bengal Cat ancestor. Serengeti Cats have long ears and long legs like a Serval, and a neck that does not taper where it meets the head. They are agile, active, and vocal. TICA classifies this cat as an advanced new breed.
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??????
