When all put together you're looking at nearly 8 feet of play center...no little plaything here. I made it so even the larger bunnies can enjoy it. The two towers are 14 inches square by 24 inches tall with ample 7 1/2 inch wide by 8 1/2 inch tall entryways. They're big enough I can fit my whole head through them! So, yeah, the bunnies will fit just fine. Then there's (3) 7 3/4 inch wide by 24 inch long ramp/bridge pieces to complete the Tower Bridge facility.
This item works great will all the other Playland accessories so you can mix-and-match them for an endless entertainment mecca for your pet bunny. The sky's the limit - all it takes is your imagination and some floorspace!
