This was awful with kittens. It's very fine, so they can't bury well with it. The grain is fine enough to get caught between their toes, so they track a lot of it out of the box, and being light, it sprays pretty far when they do so. It causes feces to adhere to their feet, which has made us have to strip the bed, clean the carpet, and wash the kitten twice. The scent of the litter, while not strong, is nauseating, especially once they've toileted. In contrast, Tidy Cat Tidy Feet Low Tacking Unscented Clumping litter works well and has none of these issues.

It does the job

It’s a decent litter for my 20 lb long haired male cat, and he doesn’t seem to mind it at all. The texture is very fine, which is okay, but it does track everywhere, definitely not my favorite part. On the plus side, it clumps urine fairly well, about 85% of the time. I just wish it were a bit more affordable for the price.

I have 2 cats and live in a smaller space. Perfumed litters are overpoweringly strong in my home, but unscented left an unpleasant aroma, too. This litter controls bad smells without covering them up with fake scents.

Hard to go wrong with Arm & Hammer. Very good odor control and clumping. I’ve upgraded from this product to the “Slide” version, since I use a litter robot and that helps keep things a little cleaner.

Best EVER for multi cat home

I finally found a litter that all 4 cats like. It is not dusty at all, you can’t smell it and clumps nice. I wish it was a little more natural but at this point

I finally found a litter that all 4 cats like. It is not dusty at all, you can’t smell it and clumps nice. I wish it was a little more natural but at this point beggars can’t be choosers. If the cats will use it then it’s a winner.

Nothing special

I have used A&H Clump and Seal for many years and been satisfied. I noticed this new (to me) “Platinum” version which was only available online. It was a few dollars

I have used A&H Clump and Seal for many years and been satisfied. I noticed this new (to me) “Platinum” version which was only available online. It was a few dollars more but said it controls odors even better. So I decided to give it a shot because controlling odor is always a main goal. I started with a freshly scrubbed litter box to get the best results. The 1st day I was surprised because it didn’t seem to be controlling the odor as well as the regular clump and seal we’ve used. I scooped and added more litter just in case that would help. After a few weeks and daily cleaning of the litter, I am quite disappointed in this product. It actually seems to provide LESS odor control. Not sure if it’s just a different scent of litter and it doesn’t smell as fresh from the beginning? Or maybe it just doesn’t work as well for us. But I will NOT be purchasing this particular product again. I will save the extra money and stick with their original line that works better. I like A&H products. This one is just a big miss for me.

We clean multiple times a day. Have 3 cats using the box. We had notices we could smell it so I did some research and found this litter was highly rated and decided to try it. So far, its great and we no longer smell the cats.
