This is the best hay feeder I have ever used. I like its size because it can hold enough hay to keep my rabbit going all day. I fill it up in the morning and then again at night before bed. He always has enough hay to nibble on. The wire part at the front keeps the hay in place, which avoids a lot of dirt in the cage. Depending on how aggressive your pet is, some of the hay may fall out as you pull on it. The hay feeder is very easy to install in just 2 minutes.
