I have an indoor spayed female DSH 6 months old. I feed her Iams kitten chow. I was leaving 2 bowls full for her to nibble on throughout the day. I started noticing her stomach was getting rounder & that flabby pouch flopping around when she runs. I weighed her 2 months ago & she weighed 4 lbs. Now she weighs 8lbs. I decided to reduce the 2 bowls of food to 1/2 cup in the morning & 1/2 cup at night, like the recommended dose on the bag. So far she doesn't seem to be eating it all and doesn't seem hungry. Am I worrying too soon about her weight?
