I have 2 cats at my fiance's house. One is around 8 pounds, the other is around 12 pounds. Recently we have begun feeding them half each of a 5.5oz can of Natural Life or Nutro wet food per day along with 3/4 cup each of Nutro Complete Care Indoor dry cat food. I was just wondering if this sounds like it's about the right amount for them to be having or if I'm feeding too much or too little? I come from a family that has always free fed our cats so finding that "happy medium" is kind of difficult for me. Any words of wisdom would be wonderful. Thank you!
