My rat Bella who lives with my other rat. they are both about 6months. I got them for my birthday from a lady who couldnt look after them any more! any way Bella is very skinny and has crusty bits around her eyes. my mum who has had quite a lot of rats in her time. says that I should just feed her up and keep the nosie down. she also said don't take her to the vets because they wont do any thing. what do I do???! please help! xx
