While it is true that guinea pigs can eat watermelon, it will be important to avoid giving them any seeds. If you do feed your guinea pigs watermelon, it will be imperative to make sure that you slice the chucks thin enough so they do not have any problem digesting them.

Although it is okay to give guinea pigs watermelon once in a while, you will want to limit the amount you feed them at one time. Guinea pigs need a lot of different things in their diet in order to get all of the vitamins and nutrients their bodies require.
