One of my rats left eye keeps getting glued shut with what I think is eye gunk (like people & dogs get too, you know?) I fix it by pressing a warm cloth/papertowel/napkin to it and eventually she can open her eye but when I don't catch it (like when I'm alseep) she scratches and it makes around her eye bloody and a little swollen. No eye damage yet but that's what im concerned about happening. Does anyone have experience with this? Also, does anyone know of a product I could use to prevent it from happening? I'll try to get a picture of it the next time it happens but shes not the kind of rat to stay still so I might not be able too get a clear pic. Do I just need to go to the vet?
