We use Aspen, Carefresh, and now Feline Pine.
We were using the Aspen alone. It was cheap but didn’t help with the smell at all. So we decided to add some Carefresh with it. What I do is mix the Aspen and Carefresh in a large garbage can which I keep in the garage.
But in a different thread, someone mentioned Feline Pine pellets for odor control. So we tried them and wow, do they work good. Right now we’re still using the Aspen and Carefresh mix, but I’m sprinkling a thin layer of FP over top of it. Once we finish off the mix then we’ll just stick with FP.
In the pans we use a thin screen to catch the poo. This keeps the buns from mixing up the poo and litter every time they jump in and out. So all we have to do is lift out the screen, dump the poo, then use a small scoop to dig out the pee clumps. This way we waste virtually no clean litter at all.
Off topic, I found these cool pans on Petco’s site while looking for Feline Pine. They’re made for dogs. I bought one to try out for Addie and Ben. On occasion one of them well pee right outside their old pan. I was thinking they were just being lazy and didn’t want to jump in, so maybe this pan will solve the problem.
