Lizzie is going to be in more discomfort than Robbie. Did the vets give her any meds for pain? It's optinal, but with total hysterectomy, she's bound to feel it more than the snipping Robbie went trhough. She should be feeling better tomorrow. It's quite ormal for them not to want food, or water for a day after. I'd say give Lizzie a kiss...but she wouldn't like that!
