One of my rats has a very large bone like lump on the back of his head/neck, it has no movement whatsoever and feels just like a bone. I have absolutely no idea what this is, I will post pictures in the morning but until then if anyone has any ideas it would help me relax. I will be taking him to the vet asap, it seems to have come on very quickly it was not visible or atleast nowhere near this size a few days ago I’m extremely worried, at the moment he seems just as hyper as usual and besides the lump hes acting exactly the same
Thankyou so much!!
