The discharge usually starts quite watery but can then become slightly brown/red tinged or even yellow/green in colour. The eyes can appear sticky or crusty if the discharge dries, which can make them quite itchy. The hamster may rub his eyes, or try to groom the skin around his eyes more than normal.
