Some hay waste is unavoidable with bunnies, but they are pretty good at finding the pieces they haven’t peed on yet. I find mine also eat way more of what’s in the box vs. the rack. I could give it to them only in the rack… but I want them to eat as much hay as possible so I don’t mind some waste. For that reason it’s important for me personally to find a cheaper source of hay (pet stores are ridiculous). One tip is to find a hay supplier that sells bales and ask if you can pick up the loose hay that collects around the bales.
All of that said, what’s your hay rack like? Some seem to like the hay “hopper” style more as the opening is larger so they can select their favorite pieces. I also noticed mine eat more hay from the rack when I don’t stuff it as full and I refill it more often.
