I just read everything. I'm so glad for your kitty. My cat Russell recently fell off the vet and luckily it was just a bruised hip. My vet told me to rest him, and the vet probably told you the same thing about your kitty.
But if your kitty wants to move around, let her, she'll let you know when it's too much for her. Or perhaps play with her until she's too worn out to go jumping around on things. That way, she still gets to move and have fun and you don't have to worry as much.
I play with Russell till he's had enough and he usually lies there relaxing or walks off somewhere else to rest. And this worked wonders after he was neutered and also when he was on orders to rest last week.
