When I first got cats, I put baking soda in the litter. Then I read something why that shouldn't be done, so I stopped. Of course, I don't remember NOW what it was that I read...
Almost word for word what I was going to say, haha!
High in sodium content and they lick their paws that get in it--probably.
That along with removing potassium and lowering acidity of blood and urine. Why I rejected it as a natural option for the heartburn I used to have.
I thought it had to do with breathing in the dust, but this makes a lot of sense too. thanks Dee.
The good news is, Queen Eva is rolling in the grass litter instead of the clay clumping, which relieves my mind a little. When I wipe her down after she's rolled in the clay, her fur is slick, slippery, yucky. Nothing like that with the SmartCat.
