Query: So glad this exists, but wish the door was sturdier.

I have been happily 2 hay holders for 3 rabbits - they get the hay out easily, and it has greatly reduced the amount of hay wasted on the floor. The rabbits still make a mess with it, but not nearly so much of a mess as before I owned these holders. One has been holding up for a year, the others' door stopped closing after only a month of use (I use a twist-tie to close it). They do take up space, so I just put them high on the cage and the rabbits reach up a bit for their hay (this occupies them longer and reduces boredom when in their cages).I've read some complaints about difficulty filling the hay ball - I just stuff hay inside it while keeping the hay ball INSIDE the bag of hay all the while, so that I'm not getting hay all over the floor!In summary, if you don't have one, buy one - it's definitely not perfect, but it's so much better than just dropping hay in the bunnies' cage or a food bowl!
