Made it worse!
I have been using this for a while now, and they are definitely more hungry. Beside the fact that these smell awful, strong cardboard smell, they absolutely love them (hence 2 stars), but instead of pacing themselves (I have 3 furkids) like they did with the other dry food, they gulp them down finishing everything immediately and not leaving anything for later, so they are hungry and nervous later. I'm throwing this away and switching back to for sterilised cats.
