All of our hutches are offered with an option to be completely protected with animal friendly wood preservative (or left natural to be painted with a preservative of your choice). If the preservative option is chosen each piece of wood is individually dipped in preservative to ensure that all the wood is completely protected. We recommend you re-proof your hutch with animal friendly preservative periodically. We now offer Rainbow preservative so the option to have your hutch painted with Cuprinol garden shades. This allows you to add some colour to your rabbits accommodation and this preservative lasts longer than our standard preservative.
