This is my first summer with a Coonie kitten so I'm no expert - Freyja gets two wet pouches a day (or a chicken breast or coley block instead of a pouch) and kibble left down all day to snack on, and her appetite has definately not reduced in this heat! Mind you, she's just turned four months old and regular burns off huge amounts energy galloping up and down our 3 flights of stairs, so she might not be the best comparison!
