Well coming from an over protective or reacting Meowmie!!!! I understand your pain....... My little sweetheart Paris just had her spay on Tuesday of last week. And it didn't go that great mainly because she is VERY SPOILED!! I realize this now but, she managed to get herself all full of her food-litter-water..... You name it she was full of it. But she is doing really well now. It takes about 4 days for her to start coming around. Quiet is a very good thing. She was just fine as long as she had me, some quite and some special one on one time we me....... If she is predominately your kitty you will need to comfort her after her vist it sort of scares them sweet?????? Once they start to come around they will be up in no time. Keeping them from moving too much is the hardest thing to do....
Good luck- My prayers are with the two of you!!
