It's an old syrian male hamster, I think it's about two. Pretty robust, it even survived a house fire!
Recently it's been drinking a lot of water and tonight I noticed its lost the fur round it's scruff and its starting squeaking :( Is there anything I can do? Or should I think about taking it to the vet?
(It was a rubbish baby substitute when we were TTC, DC1 expected in about 6 weeks).
