I'm sorry to hear that
I noticed he used his sand bath last night and ate quite a bit of the carrot food I'd left plus quite a bit of the baby food so he may be feeling slightly better, I still don't think he can gnaw properly though so I will be calling the vets later. There's not too many around here but there's three different practices of the same branch so I will be able to see another vet in one of those.
He is not my friend at the moment either
