We adopted 2 cats almost 2 years ago both from the same litter. One is a tiger and the other a calico. They'll be about 3 years old in May. The problem I'm having is when we leave on a trip, the tiger will get angry with me and chew threw electric cords, i.e. cell phone charger cords, regular lamps cords. She just chewed threw my second phone charger cord! What can I do? She doesn't do this when I'm home?
