Some injuries in guinea pigs may not seem too big, but it’s best to have your vet examine your guinea pig just to be sure. A phone call may be all that’s needed in some cases. For instance, the milky white substance you see coming from your guinea pig’s eyes can be quickly explained by your vet over the phone in most cases as the substance is quite normal. Guinea pigs keep their eyes open at all times even while they are sleeping. The eyes could get dried out so to prevent that they are moistened and lubricated with the milky white ooze that secrets from the eyes. When the substance comes out of the eyes you may notice your guinea pig will ‘wash’ his face in order to remove the ooze. This is common, but you can also read more here or call your pet clinic San Antonio, TX for more information.
