I have started a colony 1.2 rats about 2 months ago. The were all juveniles. Tonight I noticed some blood in the tub. Upon investigation, 3 small pinks were found. The bodies were partially eaten. The heads were about 1/2 the size of a nickel. Maybe all were premie? Mom did not look pregnant. Only 1 female has a bloody bottom. But she also has eyes that look gray now. Almost the color of a blind person? Any experience with my unusual observations? How do you check if a rat is blind, and if so does it matter?
TIA, NAncy
