He got a small scratch inside one cheek pouch from a sharp piece of bedding I missed.

I removed the sharp bits and cleaned the cage. What signs mean I need a vet rather than just monitoring?

Picked up my new hamster three days ago and today the droppings are soft and he is a bit hunched.

No tail wetness that I can see, and he is still eating. Is this normal settling-in or should I call the vet tomorrow morning?
