The healthiest diet for your rabbit or guinea pig is one that mimics that of their wild cousins. That means that about 85% of it should be fresh hay and grass. You may already know about hay, but what about grass?

Ideally, rabbits and guinea pigs should have daily access to grass — while grazing outside or munching on potted grass indoors. If grass is a new food item, introduce it slowly. Wild herbs and dandelions are also fine but avoid toxic plants. Also, never feed your furry friends lawnmower clippings, which can rapidly foster bacterial growth. Instead, use scissors to snip off grass and feed it right away.

Finally, don’t forget to round out your little one’s daily diet with a handful of fresh leafy greens, veggies and herbs.
