Hi im a little concerned because my hamster seems to have cut his lip some how? It doesn't look infected from what i can tell but it does worry me. I don't know if it's from his wooden chew toys or the cage bars but I'm looking into getting a larger and plastic tank or bin cage. But it may take a week or so to get it sorted.

Any advice on how to prevent this cut from getting worse or to try and prevent other similar injuries in the mean time? I would really appreciate it. Thanks.
I got this soft dog cage from Pet Street Mall and he seems to be very happy with it. It's made of plastic and its edges are well padded to avoid injuries.
