Yes of course she does! My cat never sat on my lap, ever, up until I injured my back. He then spent the next few days and nights stuck to me like glue, including sleeping next to me /on me which he had never, ever, done before. As I started to get better he gradually went back to being his normal little hairy maniac self but even now if I’m in the sofa and put a blanket on my knee he is straight up there checking I am ok ! ( and I never do this just to get him on my lap, honest 😂😂😂😂😂) They know!
She's a cat, so by definition she's magical. But if she purrs a lot, that could be helping with your pains as I've been told that the vibrations of a cat's purr can encourage the body to heal. Plus of course the instant heat pack won't be hurting the situation .
You wouldn't want my boy lying on your schedule and pains, two minutes with him on your lap and your legs go numb! I was going to suggest that's she's just targeting the warm patches where you have inflammation too
