As long as they are fresh and not frozen, your Guinea pig would love to chew on some delicious berries. Make sure they’re organic too, because just like us humans, the pesticides in conventional fruit could potentially harm them.

They may not know what to do with it at first because it’s very different from their usual diet. Give them time and patience; I’m sure they will eventually enjoy eating this new snack.
