Rabbits' Gnawing Needs
Other useful materials for diversion are hay and straw: these lead to the greatest decreases in abnormal behaviour, and rabbits by far prefer these materials to wood. There are, however, disadvantages to hay and straw. Wastage of these materials can lead to fouling of the pens and therefore an increase of disease risk. The quality of the hay is also important, as hay can contain moulds not healthful for the rabbits. Hay is, of course, also important for roughage. As cleanliness is essential, it is best to provide hay in a structure such as a hayrack.
Although the most ideal living quarters for rabbits are still those with sufficient possibilities for digging and gnawing, a good alternative can be enhancement with hay, straw and wood.
