Each pack has 14 sifting liners and 1 bottom no-hole liner. On average, in a single-cat household, you can sift every other day, so each pack of liners can last up to 28 days.
Innovative Offset Liners: Each liner acts as a sieve. When two are offset and stacked together they form a solid base which minimizes CATCHING cats' claws and tearing. It also prevents urine leakage and litter from falling to the bottom.
Use with clumping clay litter that is non-lightweight. Please add at least 3" of litter.
Most cats never or rarely tear holes in SpeedySift liners. However, a few overactive cats dig too hard, too much and sometimes might tear the top liner. Thanks to the offset-stacked sieves, you will only lose one sheet (not several layers). Please trim your cat's claws and the rest of liners will be safe to use again.
