Earlier today I was watching my female rats sleep (creepy, I know) and I found that my momma rat Tristan had some funky eye goo. It looked like blood that had kind of crusted around her eye like 'sleep' normally would. I didn't see any puncture wounds, scratches, or inuries of any sort around the area. Has any one had something like this before or does any one know what it is? None of the other females have it.
