Here's some information on Cat-Sip!
Cats love milk. But some can't digest the lactose in regular milk. Cat-Sip® Real Milk Treat is 99% lactose-free, so it may be easier to digest. Now cats and kittens can enjoy the benefits of real, Grade A, low-fat milk—that provides them with the hydration all cats need.
