I'm trying to change to some healthier food options right now, and 2 of my 3 cats act like they want to "bury" this new food. They don't do it every time, but sometimes they scratch around the plate on the floor as if they were trying to bury it just like it's poop. Mike usually does it after he's already eaten some, and Miles does it before he eats. They do both still eat the food though, but not vigorously. They definitely don't like it as much as their old food, but it's healthier for them so I've been kind of persistent. We're about 2 weeks into the new food and they're still doing this burying motion...
