Yesterday I took my 14 year old diabetic cat Stella to the vet for a routine blood and urine test. She has been treated for diabetes for 2 years and aside from that is a healthy cat. She has mild neuropathy in the back legs which does not prevent her from walking around. When they were done with the tests, the vet came out and said that they had to give her some oxygen and were letting her rest as she sort of "flattened out" as she put up a big fight when they tried to get the specimens. No, I did not ask what the medical terminology for "flattened out" was because I did not expect that it was serious. When we got home she was upset, but I assigned that to the vet's visit, gave her some food which she nibbled at and let her rest in her bed. This morning when I went to feed her, I instantly noticed that the third eyelid was exposed about 1/3 to 1/2 on one eye and she was fussy, not quite herself. I gave her the food and brushed her, talked to her, gave her the insulin, and I thought that she was on the road to getting over the visit with the exception of the fact that the eyelid was exposed of course. I then did some errands and when I got home she was moaning, making low gutteral sounds, and raising her back end almost as if she needed to poop but it was not from that. I can hear her breathing slightly heavily, but given that this appears to be progressing to something, I am not sure where it will lead and whether or not all these symptoms will become more pronounced. I called the vet and told them that she was in distress and that I needed to bring her in, so I have an appointment in about 2 hours. Any comments or clues will be appreciated.
