Can Guinea Pigs Eat Carrots
Can guinea pigs eat canned carrots?
Your guinea pig doesn't know anything that is not naturally formed. This means anything that contains preservatives, salts, artificial colors and flavors. Canned foods contain a lot of preservatives to keep them from spoiling, and while it's not so bad for humans, it's bad for guinea pigs.
Feed her only fresh vegetables, except for dense fodder and Timothy grass. And since he had just eaten a week ago, don't invite him yet. Let it sit for about a week as it will be very stressful at this time and you will not be able to digest the new food properly.
