My cat seems to be Dry Heaving quite a bit. its as if he is trying to cough up a hairball, that doesn't want to come out. we took him to the Vet to have him checked and they took some X-Rays to make sure he hasn't swallowed anything. They mentioned everything seemed to be ok and to keep an eye on him. He is eating a drinking normal.
This has been happening for a little over 36 hours. Should we take him to be rechecked? Is this something we should be worried about, or will it pass?
Any advice would be very appreciated.
