Like other reviews state here, the formula has been changed. My cat always loved Petromalt but they changed the formula and my cat won't go near it anymore. I called the company and got an arrogant response saying "yes" the formula WAS changed but they couldn't care less. Don't buy this product anymore...it's over!! Called my Vet and they recommended "Laxatone"....so I bought it at PetCo. It's drips and it's "gooey" but my cat will eat it. She likes the formula but it's messy so I put in on her paws....she laps it up. Goodbye, Petromalt!!
