My Dwarf Hamster Has A Lump Over His Right Shoulder That Seems Hard To The Touch, He Seems Fine Except For This Lump He Is Uncomfortable When It Is Touched, But Still Eats Drinks And Plays With His Companion?
I have recently gotten two dwarf hamsters and they have been quite a joy to have in our home. I'm worried now that one may be hurt or sick and I haven't seen anything happen to cause this problem. He seem normal except for the lump that has appeared overnight.
