I'm panicking slightly but I'm not sure, my hamster has these little lumps on his feet that at first I thought could be little "paw pads" like dogs have but then I wasn't sure, I don't have any wire/mesh, his wheel is flat and plastic, the bedding is clean, im so unsure!
This was the best photo I could get from his wriggling around!
Quick note! He did manage to escape last night from climbing up my quilt that had fallen into his cage, could it be from something on my floor? Carpet? Dirt?
