Is this an ok pellet for a rabbit?

This food looks fine for your bunny. How much to feed depends on the bunny' s age and weight -there should be guidelines on the package. Overweight rabbits are far too common. Make sure bunny has fresh hay in its litter box to munch ald day long and also some fresh veggies/fresh gr/greens to eat once a day. I find 1 cup a day of greens/veggies is enough for my bunny. Introduce greens gradually or diarrhea may result. Have fun with your bunny & GP.
