My hamster Perry squeaks too! he has also been acting weird where he just stops moving. His eyes are wide open, he just sits. If i pick him up he stays still. One time, it lasted about half an hour. Even when i put a peanut in a shell in front of him he didn't move, and they are his favorite! He would be running around on my lap then he just stops...
i hope its not serious.. do you know what it is that's making him act like this? Please help, its really scary!!
