My hamster gets out of his nest now and then (during the day) sitting in random places like this, doing this. I’m afraid that it could be respiratory problems. My friend suggested that he just has a lot of food in his pouches and is eating that. When he does this he isn’t very responsive as well. It’s almost like he’s sleeping because when I pick him up (and he’s more awake) he does click a little (on and off) but the weird moving goes away. I’m planning to go to the vet tomorrow but he does eat and drink.
