Untreated sea grass or maize mats from Pier One or Cost Plus come strung together in squares as inexpensive flooring and can be cut to fit your needs. Maia prefers that the mats be fixed in one place with a heavy object so she can tug at them with her teeth. These mats are completely edible. Whatever type of toy you choose for your rabbit, make sure that they are not ingesting plastic or mass amounts of cardboard, as this can be harmful. Rabbit toys can be as simple as a cardboard box or as fancy as an elaborate jungle gym.
Playtime is essential.
Encourage your rabbits to play by getting down on the floor and interacting with them. Praise them when they play with their toys instead of eating your house. You'll find that rabbits have a delightful sense of humor and thoroughly enjoy playtime. Watch and be amazed.
