We recently adopted an adorable young kitten from the local animal shelter. After a few days, we trained him to use the litter box with the Arm & Hammer product. After three successful days, he reverted to using our throw and areas rugs. We believe he was allergic to the litter because he sneezed chronically. He was not trainable to the litter box after that regardless of brand. Sadly, we had to return him to the shelter because it is not possible to have outdoor cats where we live due to predators (mountain lions, hawks, etc.).

I strongly agree with Beverlymy, I have 3 cats and their paws were also blue /green. poor kitties :( this should be under cat abuse lol

There are little blue/green crystals in the cat litter which turned the bottom of my cat's paws blue/green. That can't be a good thing because of course, cats lick their paws. I put a small amount on a paper plate and added water, and it immediately turned blue/breen. It did not to that before but they have recently changed the formula. I stopped using it immediately.

I LOVE this stuff! No more smell in my house and I have 2 cats!
