It depends. If it is a Syrian hamster they grow big over time. Dwarf hamsters are pretty small so they dont grow much (so you cant really tell). Usually you can tell, they are a bit slower (less hyper) anyway they only live for about two years.
you can tell if your hamster is going to have babies if there belly is saggy and it is not getting much exercise.
sometime you can tell if your hamster has put on more wait then usuall and is getting fatter.
tell her about the benefits of getting it
Your hamster is getting old! :(
ask the pet store you got it from or a vet
No, there is nothing wrong with your hamster. My guinea pig never runs around in her ball, and your hamster may just be getting old.
after 2 years hamsters die. so your hamster is probably getting old
Old Hamsters are Lazy, also have bad teeth then usual
Either they're getting old or they have a disease. I don't know what it's called but look up hamster health.
A hamster is old when they're about 2 years old You can tell when they're old if you don't know their age because young hamsters run about a lot but old hamsters only run a bit When I had a hamster, when it was old it was completely still for a few minitues. This is because he was tired.
Chances are, if it looks like your stereotypical hamster, it is a hamster. If it doesn't, it's a rabbit.
At least 8. You shouldn't leave a child alone with a hamster, so always supervise them.
