I used to use a hay ball for my two bunnies. One bunny destroyed his hay ball. The other bunny did not use his hay ball. I switched to a hay box (cardboard box with 3 inch sides) filled with hay. The bunnies began eating a lot of hay. After a month or two, I noticed bunny poop in the hay box. O.k., so I clean it out and its no problem. But in the last two weeks, we have noticed urinating, one time each by each bunny.
I need to change up the hay box situation, but I am also wondering about the behavior. I hate to use a plastic box. I am guessing someone out there must have discussed this before and I haven’t seen the link. One constraint is that one of the bunnies has to have a 10 lb weight in the bottom of his hay box b/c he throws the box and hay everywhere, every night without it.
Saw lots of good discussions on bunny litter boxes and it makes me wonder if I should put litter in the bottom of the hay box with hay on top? They really seem to like sitting in the hay box and munching away. Don’t want to have another litter box in the cage, but I want my bunnies to eat hay too.
