Will my rabbit fit in this hutch/cage?

it is acceptable yes, but you will be cleaning the cage a lot with that plastic bottom. i reccomend wire bottomed cages. its healthier for the bunny because he doesn't have to stand in his own droppings and you only have to clean it once a week. some people think the wire hurts the rabbits feet but it really doesn't. especially not light breeds like netherland dwarfs. sometimes heavier rabbits like giants do have problems on the wire floor. but normal and light weight rabbits have no problems whatsoever as long as the wire is kept clean and rust free. wire floors also mean less bedding, easy tray removal, and cleaning only takes 5 minutes
