Kitty Sift is a woman-owned brand. Founder Carrie Van Wert began Kitty Sift as a response to the large number of cats being surrendered due to “litter box issues” (her words, not mine).
Promising review: “These liners are easy to use and stand up well to my two cats. I’ve been using this product for over two years. Litter box changing is easier and less messy. I highly recommend!” —DebC
Price: $22.99+ (originally $27.99+; available in two sizes)
