Hi Daisey, yes they had a lot of excellent information. Guess what? The bunnies love the new litterbox HOWEVER, "mommy" is holding back progress. I only brought 1 box because I wanted to be sure they liked it. Well they still had their other 2 boxes and the other day they litterally ate all the litter out of the box! I was so concerned but I wanted to use all of my Carefresh. Didn't want to waste it. Now I will go get them 2 more "sifters" this weekend. That can't be healthy eating that stuff no matter how natural it is.
