These rabbit fence kits consist of all 1" opening size or smaller fencing and are engineered to exclude most animals including birds. The all metal version of kits are great for customers that want to grow anything that is normally eaten by birds, such as berries, or climbing animals like raccoons. These fence kits are specific in size and as a disadvantage can only cover smaller areas because of the modular structural design. These kits are great rabbit enclosure fences.
