Should guinea pigs eat all day? Guinea pigs will eat all day if you let them. They have huge appetites and are always on the lookout for things to eat and chew.
If food is left out for them, they will eat it in time.
Some guinea pigs are good at self-regulating themselves, but others are not and will overeat.
Should Guinea Pigs Eat All Day?
The best thing to do is to regulate the portions of food you give them each day, but give them a constant supply of hay to chew and water to drink.
They will be happy with this as it means that they can stay hydrated and keep their teeth ground down at the same time.
Hay and water are great for them and they can never have enough of these two food sources.
