We have been away and my two year old boy cat has been struggling to eat since we returned. He seems to want to and is hungry but mostly licks his food. Went to the vet and they couldn't see anything obvious with his teeth but gave an anti inflammatory. He started bolting around the garden when we got home and is now asleep. Does anyone have any experience of this? We were away for 2 weeks so could this be stress behaviour? Or just to mess with our heads as punishment?
