I was told I could feed my piggers Cat grass but have a hard time finding it but was recently told you could also feed them cat nip..I have heard about it but never thought a guinea pig could eat it and it be ok. Could anyone clarify this for me? I know my boy loves grass if I bring some in from outside but gets very protective of it once its anywhere near him,he would bite u from a mile away if u came near it lol.But since my place is dry and plants dont live well(electric heat) the idea of cat nip would be awesome since its already dry.
