Last night I did a total switchout of the girls' cage ( I also had bought some new fleece that I used in it). I had been using an aspen pine mix in the potties, but it was starting to get on not only my nerves (spot cleaning around the potties was getting to be a real chore with the wood sticking to the fleece) but on the girls' as well, because most of it was kicked out, and the smell control on that mix... well it left alot to be desired. So, I was digging around, and I found a quarter bag of carefresh (from when I only had a 2x4 and 2 piggies) and put that in the potties. This morn/afternoon when I went in to spot clean barely any of the carefresh wass kicked out, it smelled as lovely as a cage containing 7 adult and 4 baby pigs can smell, and spot cleaning was a breeze! Also, it looked like they had utilised the potties more since I had changed it out, so I guess the shavings had hurt their feet. SO, when I go to pick up my hay and pelletts, I know I need to pick up carefresh as well. Just had to get that out there, because my 4 year old could care less!
