I picked up Marley from a rescue organization, neutered, last May. She'd just finished weaning a liter. She's only about 22 months old now. She does not especially like to be picked up and does not cuddle nor sleep with me, but she follows me around everywhere and is always trying to play with my feet. She's not afraid of anyone, runs up to see who it is, and she barely jumps at loud noises, but instead runs up to check it out. And see if she can make it make the noise again. I have never seen her rub her head or body on anything. She does not rub against my or anyone else's leg. Until a couple weeks ago, I had never witnessed her kneading anything either. Suddenly out of nowhere she started doing it. Mostly in the morning, while I'm still in bead. She'll do the blankest, my thighs, my chest, my face. Vigorously too, like she's pumping up an air mattress. I've seen cats do that. I know it's normal, but anyone have any idea what would prompt her to suddenly start doing it?
