I have 4 baby degus(3 months and 4 months old) and 2 of them (the older ones) have very light yellow/white teeth. The younger ones have dark orange teeth. Ive been trying to give them all sweet potatoes and carrots but the older boy wont eat any veggies what so ever. Just the guinea pig and chinchilla pellets. I have never had degus before and im really scared something is wrong with them. Im trying soo hard. Is there any way I can reverse this or help them out? I change their water every day sometimes twice a day and it is fresh bottled water. Please help!
