Aww honey, I dont think Pixie will resent you. She will just be glad she is home She is gonna be fine, and happy as ever! My cats *i worked at the vet, and helped with their surgeries* woke up within minutes after the spay, and I brought them home 3 hours later when I got off work, and they acted like nothing was wrong. A little groggy BUT OH SO HAPPY to be home! Dont worry, and just get home ASAP and love on her. Make sure she is warm and comfy, and not too much activity, and I am sure all will go well. But I will send prayers just in case *HUGS* for you and Pixie! Feel Better Pixie!!

PS_ Some cats personality changes, most get more lovable and less active. Mine stayed the same
