My hamster Elvis, has a lump that keeps popping out of his right testicle. It doesn't hurt him when i touch it, he's eating and active as he normally would be.
the lump is the same colour as his testicles.
I was thinking, could it be one of his testicles moving into the other side so he has two in sack, as to say.
i'm really worried about him and i would like to know what it is and what to do, as i love him very much
thank you
