dd put George, our hamster, in his plastic ball and I told her I'd put him back in his cage after a bit. dd went out to camp in the garden and I completely forgot about poor george. Came in about 45 mins later and he was at the bottom of the stairs, still in his ball.
He seemed fine and was moving about normally (if a little nervously) in his cage when I put him back in.
Should i bring him to the vet?
