What to feed a grown rabbit that was abandoned at the park when just a tiny baby?

Question

A couple comes everday and feeds it uncooked oats. Also, the rabbit has all the "salad" it wants at the park.

Answer 1

My uncle owns a bunch of rabbits and he feeds them, hay, bread, apples carrots and the mix of grains they sell for hamsters in any pet store.

Answer 2

If the rabbit is already grown it should do pretty well on his own most of the year. In the winter give it a little alfalfa hay, pelleted alfalfa would be best, and a little grain. The less he becomes dependent on people feeding him the better.
