Cat Litter Selection Criteria
I was confronted today by a selection of four nearly-identical cat litters manufactured by Purina; as I could not parse the manifold claims in the store, I took some pictures. This evening, I stuck together a spreadsheet to aid you in selecting the appropriate cat litter.
Interesting to note that the two non-premium cat litters are easy to clean up, while the premium litters make no such claim; in absence of a claim for ease-of-cleaning, I take the position that the opposing quality is in place. Furthermore, only one litter (green) claims to not impair your ability to breathe; interestingly, it is the only litter which makes no direct claims about odor-controlling attributes.
If you live a busy lifestyle, blue is the only litter for you; however, only red has 24/7 performance. Choose accordingly. Cats (or people, I suppose) that require extreme care should choose blue; people that require instant action should choose light blue.
Feel free to download the attached spreadsheet so that you may sort by any criteria you desire.

Thanks for the spreadsheet. I’ve been faced with this dilemma since December 09 and still haven’t gotten the hang of it. Whenever I’m at the store to buy litter, I feel the same lost desperation I feel when being sent to the store for maxipads.

All my cats have been toilet trained.
Saves time and money!

I ruined Yoshi when I tried one with baking soda, for ever after we had a poop battle at the back door, and I was the loser.

But, are they clumping or non-clumping?
We usually use Tidy Cats Multiple Cats Clumping, but one day Fuzzy Kitten (RIP) decided she didn’t like it. We started getting “Dr. Darcy’s with Cat Attract”–and don’t ask me what “cat attract” is, unless it’s catnip and/or the juice from canned tuna–which made her stop using the kitchen sink. (And at least she was using an easy-to-clean-and-sanitize substitute…)
