Lately, I've noticed that when Speckle grooms Simon she licks his eye a lot until he moves his face away, Well, At first I thought his eye lid looked weird and maybe kinda puffy, but now I've noticed that he's missing fur around his eye, he's a hotot and the black fur around his eye is missing, not all of it, but enough for me to notice, I think she's being too rough and maybe even pulling some of it, I'm afraid she may be hurting him.. and he's just too nice to do anything about it.. should I be concerned?
