Well my rat has been showing signs of blood on himself i dont know how it is getting there. The other day i saw that 3 of his toenails were ripped off and bleeding. How does that happen? I have another rat that is in the same cage and he does not have any marks on him. Also he has been getting blood just under his nose its dryed out most of the time and theres alot of it. Im not sure if its blood, is it some sort of mucus?
