Before leaving my house I change into outdoor footware and leave the indoor shoes by the garage door. Mica then takes the slippers/shoes/boots to one of her beds. Recently I gave her my old slippers figuring she would be satisfied with them. Not so as she currently has the slippers and one of my boots in her bed. She never chews or damages the footware but I feel badly that she still feels anxious when I leave. Any suggestions?
