Hi Sherri-
Usually, it's the other way around - the cat that stayed home is nasty to the one that got groomed. Take and rub the short hair girl all over with a towel, and then rub the towel over the just groomed cat. This will reintroduce familiar smells to her. It will probably take a couple of days, but they'll settle down. Any time one cat leaves and comes back there will be an adjustment period.
