Has anyone used this in a cat litter box? I read that activated carbon will eliminate litter box odor when added to clumping litter.

It probably will work, it has carbon to neutralize odors and a way to trap ammonia (urine has a pretty fair amount of ammonia.) It's certainly not going to hurt to try it, the cat might even enjoy a frangrance free box.

Is this type of carbon better than the regular Diamond Blend Activated Carbon?

The blend of carbon and zeolite (the white stuff) increases the amount of ammonia absorbed and gives you a better range of capacity of a fish tank. It also extends the time between water changes, but I would only use that extra time for times when you can't clean the tank at the normal time. It gives you a safety margin and for that reason alone its worth using. You dont have to use it, but it's a better way to go.

is this more dust, pellet or grain in texture?

Grain it is more ammonia crystals than carbon. If you want a 50/50 mix buy some more carbon.

What are the ingredients, is it just activated carbon and zeolite? Or are there other additives?

Hi Annette,The label doesn't list anything except premium carbon. There is a side label on each side but it is not written in english.
