Tilly has changed so much here lately. She has gotten really aggressive.
She is starting to growl at people more often and this morning she bit the UPS man, or so he said. He seemed really ticked off. I can't handle her like this. Nothing has changed around here so I don't know what's up her butt. She is pouting on her bed because she knows mommy isn't happy with her. I also noticed her charging at our front window at passing animals, Tilly loves all animals. I don't understand. Any advice??
