Cat Litter Warning about Target Up & Up and Walmart Cats Pride brand, all made by Oildri. I quit using cat litter made by the Oil Dri company because my cat got sick and passed away. A day or two after I started using the Up & Up litter by Target, made by Oildri, my cat had the litter in her mouth and eyes, she was congested so I took my cat to the vets. The vet agreed concerning the cat litter so he treated her but she didn't get any better and eventually passed away. I now check my cat litter to see who makes it or I find out.
