"These lids help keep the little 3oz cans of cat food fresh. My Neko doesn't eat a whole can, it takes her 2-3 days to finish. (she is fed Taste of the Wild dry kibble with some wet food daily)
I was using zip lock bags, which was wasteful and I also tried freezing unused portions - the mini pet food can covers are a life saver!
Highly reccommended!"
