My guinea pigs cage is on a chest beside my mom's kitchen chair where she does crafts. She has a lamp she uses on the table and it stays on all day and every night when I turn it off for bed my guinea pig like screams. He never stops until I turn it back on then he's completely quiet. I think he might be scared of the dark and I've just realized it tonight. My mom told me I can leave the stove light on for him so he doesn't get scared but I figured he's nocturnal so maybe I should try and figure it out. Does anyone know any ways to try and make it so he's more comfortable in complete darkness?i
