Okay this might be kind of a dumb question but whatever. I have a hamster named Larry and I pay attention to it and everything but I put it in it's plastic ball thingy and I forgot it was in there and kind of left it in there too long and when I tried to take it out it was going all crazy and when I put him in his cage he tried to jump out of it and he never does that. It scared me and I felt really awful about it. I was just wondering if it was temporary and do you think he is going to be okay? Also he has a sticker of a hamster stuck to his back and I was wondering if he can get that off himself because I can't get near him. And if he can't get it off how could I do it? I don't know if you can answer those questions but if you can I would really appreciate it.

Doesn't sound to me as anything to worry about,
Use to raise Hamsters myself,
As for the sticker thing, Think of it this way,
If they get loose in your house they nibble at all kinds of things,
Doesn't seem to hurt them, most healthy animals seem to know what to avoid anyway.
He'll calm down soon, I'm sure and if not just be patient with him and keep offering your hand till he accepts it, You got to be slow and patient with nervous hamsters,

I think it's a bit weird there a sticker on its back just softly minute by sec pull a little don't worry and when its in its ball and you take it out you can tip the ball carefully low to the ground of your cage so he drops out not hurting himslef, he obviously likes the ball that's y he tried to jump out he should only be in it for 20 minutes because its exercise and keep an eye on were he's going it will maybe be temporary just gte to no your hamster so when he jumps out you can handle and after while of putting him back in the cage he'll get the jift that he's going no were everytym you put him bak in
