Your hamster is getting old! :(
he's dying :/
a. he/she is hiding food or b. you need to see a vet
If an animal loses their food source, in the wild, they will try to find a sustainable source to have food to survive. If they cannot find a worthy source of food/water, they starve or become dehydrated and pass away.
Save the hamster food
It happened to my hamster, he is probably just getting old. If he starts to lose all his fur check his food and bedding, he could have mites. Either way take him to the vet if he loses more fur!
It becomes dehydrated, or dry.
If an organism becomes extinct, the food web collapses. Every organism is needed for it to function properly.
when your hamster eats to much it could not actually be eating the food it could be hiding it somewhere in the cage but if your hamster is eating to much you should try removing the food bowl for a day or two but nothing happens when your hamster eats to much it just gets chubby.
Go to store and look at the ingredients of the food on the hamster food package.
Check your hamsters food. It doesn't matter where you get the food, how you get the food your food could have weevils. The weevils go inside the cage when you put food in there and cause irritation. Put your hamster food in the freezer to prevent this. OR, It probably has mites. My hamster had mites, and she was losing fur on her back. We were wondering if we should take it to a vet, but she ended up healing by herself and is now perfectly fine. I'm not saying this is what you should do, because your hamster might not heal by itself; she might get worse. If she loses more hair, and still doesn't seem to be getting any better, I'd suggest bringing it to a vet. I hope your hamster gets better soon!
you get a poopsicle

It dies. Although they save some food in their pouches, it is not enough to keep them alive for a whole month.
