My rabbit, Thumper, is the first I have ever had. I make sure he has plenty of hay, water, thingies to chew on, and all the kinda stuff. I noticed he started getting weird clumps of fur stuck together, generally near his mouth. It started as small pieces that were generally easy to brush out, but they’ve been getting worse. There newest one is a large piece of clear white… thing that I can’t brush out, and don’t want to even try cutting in fear he’ll be hurt. There’s smaller pieces mixed in, but it’s just more of the kind that can be carefully brushed out. 

It’s probably worth pointing out Thumper shares a cage with my guinea pig, Benjamin. I’ve been caring for guinea pigs for about six years (not in a row), so I’m sort of sure it isn’t something wrong with the guinea pig affecting him. I do have vitamin drops in the water for both bottles so the guinea pig gets enough, could this be what’s causing the sticky fur??? It’s really bothering him since he’s always trying to wash his face, and I really don’t want to risk hurting him by trying to figure out what it could be by myself. I’m terrified that he’s suffering from something… I don’t want him to suffer. He’s a good little bun-bun.
