Found a baby bunny in my backyards?

HELLO!! im visiting my greatgrandma right now and just a little bit ago i found a baby albino bunny running around the yard. It looks about 4-5 months old. its not a wild one im pretty sure someone released it into the wild. i have a pet rabbit at my house so i know wat domestic bunnehs look like. i cant pick it up because its too fast and idk if it is safe to pick up. so i just put some food out and fed it banana. the rabbit came up to me and ate the banana!! its soo cute and i dont want anything to happen to it. my granny has cats that run around her yard too so i dont want it to get hurt. i put a box outside with a whole in it so it can stay in there and be safe. im just wondering wat should i do? my parents said they'll call the animals control people. any advice?
