We use Tidy Cats in the big container. I really like it because of the odor control and my cats seem to like it as well. Also, it clumps amazingly.
We were using Feline Pine for the first few weeks because that is what the adoption shelter used, but I hated cleaning it out. It took about 30 mins to clean out one pan because the pine pieces dont sift out, so you end up throwing away a lot of litter if you aren't careful. I would have to sift the
"saw dust" which is what happens to the pine pieces when they urinate and scoop that out, then sift out the feces. A lot of times I would get so frustrated I would just dump the whole thing, which got really expensive.
I am really happy with Tidy Cats and I know a lot of people that are happy with Feline Pine. As Ghosttown said, the cats have to like it, first. I was really nervous switching, but my cats love clay litter because they are buriers, which isn't something they could really do with the Feline Pine.
