We had one who was really sorry for herself, I was in tears as I felt so sorry for her, like you slept with her in our room for a couple of nights (Bungalow, no stairs). The other one was trying to jump into the car on the way back from the vets - she was more trouble because she wanted to jump about, and to think I put off spaying her because the first one upset me so much :-D
Took about 12 hours for them to get over the anaesthetic completely I think, then they were both fine.
