Glad her op went well and I agree thats a tiny shaved area!
The lamp shades are a bit of a nightmare but are also designed as to not let the cat rush about and jump etc....Im sure she will still have some pain relief running around inside her that has'nt worn off yet....
Im a worry pot and always leave the shades on for about 5 days!
You could try raising the water and her food bowl for her!
She is gorgeous btw!
