@helanorms- what's actually IN this "natural cat litter" you're asking about? When it comes to advertising, the word "natural" is meaningless- it's used to make you assume that whatever they're selling is "safe"- so let me just remind you that many things are perfectly natural but far from "safe"- arsenic is natural, so is radon gas, & strychnine. See?
I've seen cat litters advertised that have color changing crystals to diagnose your cat's health from how their pee reacts- I wouldn't think that would be safe litter, but there are plenty of other mundane cat litters that might easily contain substances that could make ASFs sick when used as their litter. They're perfectly fine when used for their original purpose, just not safe to use in alternate ways for other animals.
Even some products deliberately sold as animal bedding can be problematic- such as cedar shavings. At least you can read the labels, since you work there, then research any ingredients you're not sure about. You always have to worry about what small animals will be inhaling from such products, not just whether they'll try to eat it.
If you see a product elsewhere, like on Chewy, that you want to try, maybe your store will order it for you, if they don't already carry it. Chewy carries many things for sake of comparison.
