I put a nice box with a pet safe heating pad and blanket and the cat never sat on my keyboard again. When she wanted my attention she then just stood in front of my face and then would sit back on the blanket eventually

Yep. I have one of these on my desk: https://www.amazon.com/Generic-Cattop/dp/B09F8QQPJH/ (a heating pad shaped like a laptop), and our cat will spend 90% of my workday on it, and the remaining 10% is spent getting my attention (or getting lunch).
