Can guinea pigs eat frozen red bell peppers?

Yes, guinea pigs can eat frozen red bell peppers, but it's best to thaw them first to ensure they're safe and easier to chew. Red bell peppers are a good source of vitamin C, which is essential for guinea pigs. However, moderation is key, and they should be given as part of a varied diet that includes fresh vegetables and hay. Always monitor your guinea pig for any adverse reactions when introducing new foods.
