dry

My winter white dwarf hamster, Prima, has been having unusually dry poop on & off lately. Today, it's not dry & the consistancy is normal, but it's abnormally small. She's acting fine, but what does this mean? Should I be worried?

I'm hoping someone would be able to help me clear something up. My chin has scaley, dry looking skin on the backs of his ears. I will post pictures tomorrow... Could someone help me figure out the difference between a fungus and dry skin? There doesn't seem to be any irritation or red blotches...
