I just got a young white dwarf rabbit with red eyes a week ago. I don't know her age but she seems to be pretty young. When I got her she was completely clean and now a week later her mouth is completely brown, wett and matted. she constantly tries to clean it with her paws, but her paws are dirty as well and it just makes her face even more messy. Her cage is the same cage that she was in in the store, same bedding, same food and i've already changed her bedding this week. She is a very good, lively, curious bunny and seems healthy... (eats and drinks constantly, normal pool, clear eyes) but she seems to have trouble keeping herself clean. What is weird is that this is a recent thing since she seemed to be able to keep herself clean in the store. I thought maybe she has a cold and a runny nose and it dirtys her face? but as i said before, she has perfectly healthy behavior. she also clicks her teeth a lot.. could this have anything to do with it? I've had rabbits before and never have seen one so bad at keeping herself clean... any advice will be greatly appreciated!
