Drill or cut a 'feeding' hole near the bottom, small enough that your bird's head can't get stuck in it. Next poke or drill a hanging hole in the lid. Lastly fill it with hay or paper shred plus seeds and treats throughout!
DIY treat - freeze your guinea pigs or bunnys favorite fruit or veggie treat into ice cubes and give them as treats. This helps them cool down on summer days. Remember to always check with your vet before introducing human food to your pets.
I really need a solution for getting the hay off my the floor of my bunny rabbits cage, I had a hay holder (plastic) but he refused to eat from it. Since he likes chewing on cardboard I think this might just work! fun for a gerbil toy
