Hey small pet owners! This 4-pack of metal hay feeders is exactly what you need to keep your bunny or guinea pig's feeding area clean and organized. Each rack measures 9.1 x 3.9 x 3 inches - plenty of space to store enough hay that you're not constantly refilling it. The sturdy iron construction means these things will last through all your pets' chewing attempts. Installation is super simple - just hook them right onto the cage bars and you're good to go. The hollow mesh design is genius because it stops your pets from tossing hay all over the place while still letting them see and smell their food. Works great for rabbits, guinea pigs, chinchillas - basically any small animal that needs hay in their diet. The black color looks sleek and won't stand out too much in your pet's habitat. Seriously, if you're tired of cleaning up hay messes every day, these racks will save you so much time and keep your pet's eating area much cleaner. Plus with four in the pack, you can place them in multiple cages or have spares ready to go.
