Pet's info: Other | Unknown - Other | Male | 5 days old

I just adopted a hamster almost a week ago at Petco. He's been sleeping almost all the time and I haven't seen him eat much. I am up pretty late most nights so I don't think he's just eating while I'm alseep. Is he ok? Most hamster I know are super active at night.

Its hard to say if Pepper is sick without more information. You are correct that most hamsters are active at night time. They usually like to run in their little wheels and scurry about the cage. You need to watch for any signs of diarrhea or wetness around the rectum. When Pepper is awake, are his eyes open or half closed? Is the food being moved around? Many hamsters pack the food to their nest to eat later. Also, offer the pellets as well as the seed mixture. When he is awake, is he active? Most pet stores have a health warranty on their little critters. If you are seeing signs of illness, call the store to ask about having Pepper checked out.
