I'm dealing with my rodentologist, he's on 0.2 calpol a day and we thought it was because of a dodgy leg or maybe arteritus, it went away, he came off calpol and was fine for a while and now he's back to look puffed up, not getting up very well and feeling very skinny and sometimes cold. He eats, drinks and is cleaned out regular, he stills walks about and seems normal with how he moves just a lot slower, his breathing seems strained and he feels stiff when I pick him up, like it's an effort to be held then he sleeps when I'm holding him.
