As an update from my last(and first post), no, my parents are still unwilling to take my hedgehog to a vet because "he's old and he's going to die sooner or later anyways." I did convince them to buy a syringe so I can start syringe feeding him though. I think my hedgehog is having respiratory infections, since he's been having a runny nose and doing weird breathing sounds. He's still really active though. Despite not eating a lot ...is there anything I can at least do at home to try and help him?
