Is my hamster sick?

[Paulina]

Hi guys i am worried about my hamster, if you have read my posts i got two wither white dearfs ( from a pet store so most likely a hybrid) one was always more active , eating well pooping and peeing fine he is a bit fisty i cant touch him yet altough he stopped aquiling at me so we r moving in a right direction. The other one is whats worries me his behavior from the begining was a bit off. He wouldnt come out of the house almost at all. Not eating much, i had to finger feed him, crash his food , i know he is eating something cuz i can see dropings in the cage. Last week he started changing color of his fur ( he was white with some light brown/ cream markings now it seams he is turning more white with each day. He also started to eating less, is less active even if he comes out of the houses he falls asleep , i also think he is breathing really fast ... i will try to link a video i took today of him ...is he sick ? Could it be he was starting to hibernate ? It was very cold last week where i am, he isnt cold to touch, but i think he looks like he lost some weighy too... i

It does sound as though your ham is unwell, a lack of appetite & activity isn't a good sign but it's hard to tell what the problem may be, have you spoken to a vet about him?If not I would contact your vet & see what they say.
Changing colour is normal so that's nothing to worry about.
Hamsters don't hibernate, they can go into a state of torpor which is very serious as they can die so it is important to keep the room where they are warm at all times.
