We recently created this Hay Feeder for our Guinea Pigs. But it is definitely great for Chinchillas and Bunny Rabbits too!! It does not need too much space, will fit in most places, but holds decent amount of hay.
The design is very simple and sturdy. You can attach it to the cage, Mounting Hardware Included. You can mount it however high or low depending on your bunnies / piggies / chinchillas wish and also use any size or type of litter box under it.
However, it stands stably on the floor too.
Not to mention, that price we keep as low as possible!
2,56'' / 6,5 cm
Hay feeder is made from Solid Kiln - Dried Wood / PINE
