We tried these wet pouches because when our cats were smaller they were on the Nutro canned food when they were smaller and we had switched them to an organic brand that was probably a bit better for them, but smelled awful (looked a bit too real too).
The Nutro pouches that we use are meant for indoor cats and there is a huge difference in litter box smell. That may not matter to some people, but when you have to 2 cats in a smaller apartment, every little bits helps!
The only down side to the pouches is if your cats are like ours, they like wet food in the mornings when you are half awake. I have been squirted by the liquid a few times. Not a horrible thing to have happen, but one of the reasons we use the wet food is for the additional moisture. Of course, cat food isn't the best odor either.
