You know, I honestly feel so bad disturbed and frustrated, horrified by your threads and I feel that many people on this site feeling same, you are trying treats, vegs, different critical cares when you don't really need them all, what you need is to get enough hay and feed your rabbits regularly and don't give them some strange treats or something that would upset their bellies.
It is not funny, they are not toys, you spend all your money on treats and then you don't have money to buy hay so your rabbits have no hay for 4-5 days, what'd you expect? You wouldn't survive on candies if you get no other food, would you?
I feel really bad for your animals, poor rabbits.
