I have an 11 year old lop who is eating well and acting healthy, except for some hind end weakness that has come with age. However, last night I was cleaning her ears and suddenly felt these lumps, the size of grapes under where her ears meet her head. When her ears hang down, it covers the lumps. You can't see them, but you can definitely feel them. I have never, in all this time, noticed them before and am wondering if this is a normal part of rabbit anatomy or if they might be tumors or abcesses. The lumps are softish and slightly movable under the skin, but they alarmed me. I can't believe I've never noticed these before, but I don't usually lift her ears up and feel there. Don't want to take her to the vet only to find out that those lumps are supposed to be there. Anyone??
