Our dwarf hamster who is around 18 mths old has lost what I'd say a lot of weight, he looks more bony, is lighter than what he usually is, he use to be quite a chubby, biggish boy, last night I was alarmed just how bony & light he really was. But, he's eating, a lot. He's been eating through two whole food bowls a day sometimes.
He's also shown some eractic behaviour, especially at night - I know hamsters are nocturnal but he's been acting quite unusual. He's been trying to climb onto of his wooden house, then cling into the wire lid & bite it, to do this he's hanging on, swinging - but he's not always successful & falls a lot, no matter how many times he knocks himself on his wooden house he'll do it. He's only just started to do this this!
So couple with the weight loss & the desire to bite the wire lid, I thought maybe his teeth need clipping - I know he's eating but I thought maybe he's needing to constantly grind his teeth on food or something- but how can he been loosing weight if he's eating?
I was quite worried last night. Was hoping to take him to the vets today but the weather looks like it's getting worse. Anyone with any experience of this?
