Ah this looks like an awesome alternative. I spend big bucks on kitty litter every month only to have it smell like a field of artificial flowers in my bathroom. And my cats have this thing where they like to kick the litter all over the floor and then it feels like i'm stepping on a pile of baby powdered Legos every time I go in. The only issue I have with this is baking soda isn't that good of a deodorizer by itself. I mean at the beginning you won't really smell anything but it loses its effect fast. And then the only thing you'd be able to do after that is add even more baking soda except you won't be able to knead the new amount in(unless you don't mind kneading cat urine). Also the pellets she showed looked too big. The thing with cat litter is they need to be small enough to absorb the liquid and stick to the poop. Those are too big. She should have considered adding some clay to the mix as well. You can get a big bag of the stuff from Home Depot or Lowes. Clay is a super absorbent and can also help minimize certain odors. Another thing would be to add some flower petals(like lavender) to the mix so it smells a little better starting off. Deodorizing litters are nice, but it's even better to deodorize and add a better scent to the air. Shredded fabric is also another alternative. I used to volunteer at an animal shelter so we'd have to get really creative when we would run out of our month's supply of litter.
