Thank you for your reply and I will take him to see a vet as I wondered if the cause was either, I think you call it 'cage paralysis' or whether he has a lump / mass as he literally falls onto one side if he overbalances and then struggles to get up. He is also struggling to climb his ladder in the cage and so I have moved his food so he can get to it.
Hi Dr Kara
My hamster, Fudge, sadly passed away on Saturday morning which was upsetting but at least he is no longer in pain.
Thank you for your help as it helped me prepare for what I knew could happen and as he was our only pet, I will not need to applying for a monthly subscription but I was highly impressed by the service provided.
Many thanks again.
