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.
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.
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??????
