Since this horse bedding is made from wood fibers, it’s relatively safe for cats. But keep a couple of things in mind to ensure your cat’s health:

• Check if the type of wood pellets contains any harmful additives. You want 100 percent natural wood, preferably pine, cedar, or oak.

• Ask if the equine pellets are kiln-dried to remove phenols. Phenols are dangerous for cats since their livers can’t break them down. In large amounts, they can be deadly.

• Ensure that the wood is not treated with any chemical additives.

(E: personally, though in the UK, I buy Cat's Best pellets. Probably more expensive than horse pellets, but they come in smaller packages I can manage, and are 100% safe for cats so I don't have to worry)

I treat 'em like kittens but all adults ;)

Pine pellet for horse stalls is definitely the correct answer. It's the most effective, easiest litter AND it's monstrously cheaper.

I've tried maybe 5 or 6 different litters, nothing absorbs as much smell as pine pellets. You can ignore it for a couple of days without issue. It doesn't track or clump. You don't have to scoop pee, although you should give it a quick stir or sift daily. That's easy enough to do when you scoop any poop.
