What do i do with my gerbils bleeding eye iknow its blood?

Well you need to take your gerbil to the vet and have him look at it so he can see if there is anything still in the eye that is making it bleed. Because you might not be able to see something that he could with his tools that he has at the office. And also you don't want to take anything out of it's eye just in case because you could make the gerbil blind. Where he has the medical schooling to know how to do it with out hurting the gerbil. Good luck
