@MrCavyMadness, that's likely just where Benny goes to sleep and eat. Most house bunnies are given free range of the house, or at least of the room their cage is in. Although you are correct in a sense, it's not big enough in that it needs to have two levels, and that platform doesn't count as a second level. But we can't see the length of the cage, so it's not fair to pass judgement on that.
@Princess_Piggie, You're right and I'm sorry, but I do know what cage that is because my cousin used to have it for his guinea pigs and I told him to get a c&c cage
