On Halloween (Last Thursday) I took my 12 1/2 year old cat, Baby, to see the vet for excessive vomiting. We had her shaved the week prior and she had been vomiting 1-3 times a night. He thought she had a intestinal virus that she may of caught while being groomed there, gave her a shot of antibiotics and some in pill form to take for the next week. Told me to call on Monday if the vomiting didn't stop and they will do x-rays and blood work for other issues. Well she was doing fine until Tuesday night and it started again but now it is just a clear or white vomit, before it was whitish yellow. She has been drinking and eating some but we have noticed she hasn't been pooping also. Starting to worry what is going on...Has anyone else had this happen to their cats? What can it be? An obstruction? FYI-She is a totally indoor cat and always has been and I will call the Vet first thing in the morning.
