I thought Jackson was done growing. He reached 12lbs by 6 months old and stayed at 12lbs up until he turned a year. At about 1 year 3 months old, we went to the vet and he was 16lbs! All muscle, because he's not overweight in any way! As of yesterday, he was 16.1lbs.
Here's Jackson next to my friends 4.5lber Bandit. For size comparison!
