GIANT Chicken Coop Rabbit Hutch Hen Chook House Easy Access, both run and house has large doors for easy clean. Sliding door for living area, with internal door can be opened or closed from outside of the coop with the rob.
This was made for a very loved tortoise but could be adapted for guinea pigs with wire or a cover over the top to keep out predators. For me, it would just be an outdoor playtime cage only with supervision.
Neat Idea but I've heard rabbits can get bad diseases and Parasites from being kept on the ground. Rabbits can be the King of their bunny kingdom with this easy to make rabbit tower, they can shelter underneath too.
