I have a Mini Lop buck who is 11 months old, and one side of his face is swollen. It seems tender when I try to feel of it, but he is more tolerant of hubby feeling of it, and hubby says it is a "lump." The bunny is eating and drinking (and peeing and pooping) normally, but has not been as active as normal. This is a house bunny who hasn't been in contact with any other bunnies, and I don't know what to do for him (or even what it is!). This bunny is from someone who breeds responsibly and even shows (and wins), so I'm pretty confident it is less likely a genetic problem. I have a message in to the breeder but wondered if anybody here has any ideas while I'm awaiting an answer? All responses will be GREATLY appreciated!
