I use silica kitty litter in my humidors! Lol! We will be getting a cat soon though, you tell me what brand I should be buying!
Any product you feel comfortable using for your felines. Where would you shop for your litter? Wal-mart is Special Kitty or Litter Clean and Sam's Club is Litter Clean. I can't remember which labels go with which stores. Theres too many lol.
Make sure it's not scented crystals lol. Also something everyone should know about when it comes to silica. The dust from silica can cause hardening of the lung tissue and several specific types of cancers and infections in the lungs and other parts of the airway. I can't remember exactly what they are but when I had my orientation they told us that the levels in the plant are around .05ppm (less than one half of a percent for every 1000gal of air volume is what it works out to apparently). Just be wary of using it in and around things you plan to put into your mouth. Silica is toxic to our liver and kidneys if injested in small quantities.
We also have a wet dog and cat food line but that is mainly sold in EU. We do make dog treats at my plant (like milk bone) for private labels such as Compliments, Waggles, VitaLife and I can't remember the others. It's been about a year since I worked in the bakery and they have changed some of the products they run on that side.
Does anyone use those products for their K-9's?
