I was just wondering when I need to lower the percentage of how much I feed my cat. He is a siberian forest cat and is almost 6 months old. Do I continue to do the 4% amount until 12 months?? Are there any guidelines? He is on an commercial raw diet - I feed him before I go to work -- when I get home around 6:30 then a snack around 10 or 10:30. Thanks in advance for any advice.
