Our Disco is a fantastic kitten and loveable and playful but recently if I'm doing the dishes or preparing food or holding our older cat Sonic ( who loves to be picked up and snuggled over laying next to you) Disco has started launching at my leg or backside and hanging off me. She doesn't do this to my boyfriend or his kiddo. It's quite painful and she gets tons of love otherwise. What would bring on this sudden behavior? Just attention seeking or jelaousy?
