hello every one.i was massaging the base of my little moo's ears yesterday when i found a grape sized hard lump just below her left ear.i rang the vets and have an appointment for 10.30 a.m tomorrow.there are the two obvious things that concern me-a tumour or an abcess.a tumour would obviously be the very worst thing but also i have only experienced an abcess with my very old bunny elvie-woo and it sadly meant that after a while i had to let her go.moo is only 4 yrs old,so if it was an abcess due to dental probs e.t.c would there be more chance of it being operable in a younger bunny?understandably i'm worried so any advice would be great please.thanks alot.
