My 9 year old neutered ginger (inside/outside) Tom seems to have lost all interest in food, in particular meat-based tinned or pouch food. We have tried a variety of different brands and fresh foods, but at most he will try a bit and leave the rest. He seems to prefer biscuits but is not eating much of them. This has been going on for a few weeks now, but he does not seem to be losing weight and seems his usual self in all other respects. He does, however, seem constantly hungry. He has been sick, but only a couple of times.
Any ideas what could be the problem?
Thanks, EC
