I know that the hay cubes are ok for bunnies, but I agree with Leaf. I have a whole bag of hay cubes that I got awhile agoat a show - my bunnies haven't touched them. They don't like them. I need to see if they're still good or not, because I obviously don't need them for my bunnies, but I know some other places would love to have them.
Also, you'd have to give them alot of hay cubes to equal the amount of hay you give them, soloose hay is much more better than having to spend lots of money on those small bags of hay cubes, when one package equals the daily amount of hay being consumed.
