I would hold off on the boosters until you know for sure that she's okay
If she were to have a reaction to the shots on top of whatever else is going on, it might be too much for her little body to handle. Please ask the vet to wait, even if it's just until next week. It won't hurt.
I hope that she isn't really hurt and just bruised something. Poor baby! They are SO squirmy. An acquaintance of mine was holding Luna when she was smaller and sitting on the wood floor, and she just FLEW out of her arms and fell. Luckily the girl was sitting down. She cried and shook for about an hour, and then she was fine thank God. After that, I don't let anyone hold her
All my kids know how to hold Luna so that she can't jump, by wrapping their hand around her chest with a couple of fingers in front of her paws, on her upper chest below her neck. Might want to practice that, though she might never jump down again after this scare
thinking of you guys
