Teats are the equivalent of a human's breasts, babies drink milk from them.
Your guinea pig will drink it's water
ONLY guinea pig milk. Their mom will feed them her milk and then teach them to eat solid food.
NO , please do not do this. you only give guinea pigs milk if you have to like if the mother has rejected it and it is under 4 weeks of age. but if your guinea pig is over 4 weeks of age, then you have no need to feed it any sort of milk at all. But if your guinea pig is under 4 weeks and it's mother is no longer with it, pure goats milk is the best for it. Hope this helps.
there systems aren't built for milk only there baby years you could give he/she some unsweetened juice
