Back in May of this year we suddenly lost our cat to what was later found to be a form of pancreatitis. Our cat's only symptoms were occassional vomiting. Other than that there was no cause for concern. Our other cat (the sibling of our other cat) is now vomiting occassionally too. What are the chances of this being the same condition? The other odd thing is that after almost ten year Gerber who never meowed, now meow at night all the time. He stops if you pet him. I have palpated his belly and he does not seem to be in any pain or have any masses. Our vet thinks this is meowing (the way it sounds) is a form of loss or grieving of his litter mate. What do you think?
