Long term prognosis for recovery of your cat will vary from cause to cause. Infections and pneumonia are serious illnesses that need a high degree of specialized veterinary care. In all cases, your cat’s chances for a full recovery will increase if immediate veterinarian care is sought as soon as initial symptoms are detected. Additionally, given the seriousness of lung and breathing issues, you should follow up after symptoms in your cat have resolved in order to prevent potential recurrence.
As with all non-domestic hybrid source breeds, some Chausies may inherit intestinal tracts similar to that of the non-domestic ancestors. The intestinal tract may be a little shorter than that of the traditional domestic cat. A shorter intestinal tract is thought to be less capable of processing ingredients derived from plants. That would include any kind of cereal, as well as vegetables, herbs, and spices. Those ingredients may serve as triggers for chronic intestinal inflammation and eventually lead to chronic inflammatory bowel disease that is perpetuated by multiple allergies to proteins in commercial cat food.[9] Regardless of the cause, Chausies do seem somewhat prone to developing food allergies. To prevent this, breeders advise Chausie owners to feed only very high quality commercial cat foods, containing as little of plant-derived ingredients as possible or advise feeding homemade raw or cooked meat diets with appropriate supplementation. If homemade diets are fed, it should be with the guidance of someone experienced in preparing them, because meat by itself does not contain all the nutrients that Chausies require.
In 1900, Carl Hagenbeck crossed a female leopard with a Bengal tiger. The stillborn offspring had a mixture of spots, rosettes and stripes. Henry Scherren wrote, “A male tiger from Penang served two female Indian leopards, and twice with success. Details are not given and the story concludes somewhat lamely. ‘The leopardess dropped her cubs prematurely, the embryos were in the first stage of development and were scarcely as big as young mice.’ Of the second leopardess there is no mention.”

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??????
