I tried pelleted litter, my cats hated it. One of my cats was declawed (before I adopted him!) and I read online that declawed cats often have issues with litter because their toes stay sensitive after declawing. I kept trying different varieties of litter until I found one that he liked. It's made of finely ground walnut shells, almost like powder, and worth every penny. It also smells good longer, and clumps without added chemicals. I buy it when they go on sale, and one bag lasts for months.I would think pelleted pine bedding would work great if your cats accepted it as litter. Like changing over to many new things, maybe you could gradually mix in more and more of the pelleted pine bedding into your current cat litter, gradually training your cats to the new pelleted pine bedding litter. Just my guess, as I have never owned cats myself. But I think it might work.
