This might be a dumb question, but can rats have fat lumps? Or fat balls?
My albino Pearl who had a mammory tumor under her right arm had surgery to remove it, and healed well. I've noticed there is another lump of some sort forming on the other side, and when I go to feel it, it's not connected by a stalk or anything (which the vet had told me is a sign of a tumor).
Any advice for the worried rat mommy? I haven't called my vet about it yet, and it doesn't seem to have grown - the mammory tumor definitely grew quick but I got her the surgery pretty early cause I didn't wait for it to grow any larger.
