Best non tracking litter?

We already have a litter catching mat, covered litterbox. We have two cats. The litterbox had a filter for the top, but the cats wouldn’t leave it alone lol 😒

Also, I used to have two other cats a few years ago, but they’ve never pooped and peed so much as the ones we have now.

So far the best thing we’ve tried is the fresh step clean paws low tracking litter. But it’s kinda pricey.

I’m just wondering if there’s something better/cheaper?

TIA!🐈
