Such a great company, wonderful at customising especially depending on your bunnies needs! Mine likes to stick his hole head into his hay rack, which if the holes are not wide enough he can get stuck! They were able to quickly help me with a solve and now he’s a happy bun (and I am too) the castles are wonderful and free from icky things whilst still being sturdy. 100% recommend for any rabbit owner. Safe cute and fun housing for your bun!
