You've come to the right place if you want to learn how to stroke a kitten or if you're just looking to improve your kitten stroking technique.
Let the kitty get comfortable with you. Perhaps let it sniff your finger, or play dead so it doesn't consider you a threat.
Pet the kitty's head lightly with your fingers. The kitty likes it when you pet its head.
Run the palm of your hand smoothly along the kitty's neck and back, in a movement towards the tail, then repeat. DO NOT stroke from the tail to the head. Kitty no like that!
Avoid the tummy. You may think it's funny, but kitty no like strokes on the tummy. Kitty is likely to wrestle your hand and scratch it all up.
If the kitty headbutts you or jumps on your lap, it wants more stroking.
A purring kitty is a happy kitty.
