I’ve used So-phresh™ cat litters in Athena T. Cat’s box for several years now. Clay, paper, odor-eating, and pre-shredded, pretty much everything beside the special crystal and the litter for motorized cat boxes (built-in pooper-scooper). I’m quite satisfied with all of them.
Most of the time, when it is available* I use the pellet, either with or without odor reducers. Athena doesn’t care, and I add a little baking soda to her box anyway. She is high-throughput because of her kidney-care diet, and because she’s always drunk a lot of water. This means her litter has to handle a lot of liquid output, which the pellets do quite well. They last 7-9 days in a semi-well-ventilated space, stirred at least three times a day and sifted at least twice a day. The pellet litter doesn’t scatter as much as either the clay or the pre-shredded.
The scoopable clay is your basic clumping litter. It holds a lot of liquid, and you sift out the solid waste, then collect the clump and put it in the trash. I did not notice much odor from the trash (open-top wastebasket in area with low airflow.) In theory, you can just add a little extra litter as needed and never take out the cat box, but I changed it weekly even so. Like other clay litters, it tracked, even using an anti-track mat. And you have to be very, very careful to sift all the clay away from solid waste if you flush the solid waste (some areas do not allow this, so be aware of local rules). It captured scents well, and handled her outflow.
The pre-shredded paper pellets are for cats with sensitive paws, or those that are a little weaker. I got it because it was the only thing available. Shipments have been off and on, and so I tend to grab a sack whenever I find what I use in stock (can store in garage). The local pet palace had been out of all paper litter for a while, so I saw this and bought it just in case. It works. It tracks, and it feels as if there is less litter in the box, even when I fill the box to the usual depth. It dries faster than the pellets, and the scent is no more or less than with the usual pellets. The store got a few bags of pellets in last week, so I grabbed a sack. The shredded litter seems to last a shorter period of time for the same volume in the sack, since it is fluffier. It costs the same as the pellets, so if you have a choice and don’t need lighter-weight litter, I’d go with the pellets.
I’ve used the wheat-based litters. Other than a repugnance to use food as cat litter (I know intellectually that it’s not the edible part of the wheat, but it still irks me), the dust has been a real problem with all three brands of wheat-pellet litter I’ve used. Other people don’t seem to have a dust overflow.
So, I’m pleased with all the variations on SoPhresh litter I’ve used to date.
