Key-key has a bump right in the middle of her lower lip!! It looks like she might of been trying to eat a bug and got bit! Thats is the only thing I can think of! She is fine she is eating and acting like her self!! My husband said we will wait a little bit and see if it goes down and if not we will take her to the vet!! What could it be? Could she have bit her lip I no she ran right in to the bar head first!! Oh and by the way a coulpe of days ago she started losing her teeth! I dont no if that means any thing or not!!
