Hi, I have a 10 year old cat that I adopted 1 year ago.
He is an indoor cat and we have been feeding him science diet senior food for indoor cats.
For the year that I have had him, he has never vomited before.
Recently he has been vomiting up his food many hours after eating it (ie. if he ate at 7pm he vomits it up at 3am).
The vomit seems to only contain food, no hair in it, and the food doesn't seem to be very digested(only slightly broken down) even though its been so long after eating.
It has been 3 days, and the first day he vomited 3 (once very soon after eating, then later) times, the next day a little less and yesterday just once. I thought at first he had just eaten too fast but after happening a few times I realized that wasn't the case.
What could be causing this to happen? Should I continue to monitor it or should I take him to a vet?
