My male dwarf lionhead, Babi, has a white cyst on his left upper lift on the inside.
I have already made a morning vet appointment for him this coming Saturday. I just saw this today, when he was flopped. He definitely did not have this a month ago, when he was last seen by his vet. He also only has that single cyst on the inside of his upper lip, not anywhere else on his body. He’s been his usual self: eating tons of Timothy hay, munching on his morning pellets and his dinner salad of arugula, baby kale, cilantro and/or baby lettuce. He’s quite active as usual. He is pooping fine. He’s not showing any signals of pain or distress from what I’ve observed.
Here is an album of his cyst and Babi:

I have had him since last summer. He’s roughly a year old. He was neutered this year. He also had a severe case of molting/shedding due to being underfed pellets. So the vet gave him Revolution that we administered at home for 3 weeks and increased his pellet intake. His fur has grown back thicker and lusher, and he gained back his normal weight of 3.1lbs.
Sorry for the unnecessary details, but I am really worried. Has anything like this happen to your bun?
