My lovely little piggy has been off his food for over a week and a half now. He is still really bright and interested in food, squeaking when we chop things and running to the front of the cage when we're in the garden pulling up grass just as he always did. When he actually gets the food he can't seem to get it into the back of his mouth and swallow it. He's been a bit damp under his chin, wee and poo are normal (a bit less because of reduced food intake). He had lost a bit of weight initially when we hadn't picked up that he was food refusing but now we're syringe feeding him that's stabilised.
All this sounds absolutely classic for teeth problems but he's been seen by two different vets and his teeth look entirely normal. The first vet examined him under anaesthetic, had a really good look down his throat and couldn't find any issues at all.
Does anyone have any experience of anything similar? We're a bit stuck with what to do next.
