With that knowledge I would feel confident its safe in a litter box. If you used actual kitty litter with it, even if it was harmful you probably wouldn't be using enough to actually harm your cat. **Q: Is this zeolite hydrophobic and is the pore size known?** A: Thank you jwil, for your question! This is a natural product, so the pore size is variable, but the average pore size is 4.0 Angstroms on average, and this product is not treated to make it hydrophobic. Please let me know if you have any further questions! **Q: In addition to ammonia, will it also remove ammonium (produced by Ammo Lock converting ammonia to ammonium) from the aquarium water?** A: I didn't have much luck in regulating in the tank, but I also had removed all stones and natural algae beforehand, so Im not the right one to answer this question **Q: I'm medicating my tank will this interfere with the medication ? Thank you** A: No, this will not remove medication from the water, only ammonia. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works well and is more economical *by T***E on July 18, 2026* Using this in my litter boxes, both with the traditional litter and breeze/tray style. It seems to be working quite well. At least have realized I don’t smell the odors like I used to. ### ⭐⭐⭐⭐⭐ Works well *by A***R on July 20, 2026* Great price,works well with activated charcoal in my 70 gallon tank filter ### ⭐⭐⭐⭐⭐ Keeps litter box odors in check! *by K***E on April 8, 2026* I use this for odor elimination in the litter box area. I put it in a mesh bag that is attached inside the litter box hood. It works great and is cheaper than the exact same product sold for odor elimination purposes. It isn't dusty, it's a great size, and super easy to use.
