Abigail and Amelia are both Indoor cats but Abigail wants to go outside really bad. So bad that she tries to go every time the door (front door not screen) is opened. Sometimes she gets out and I have to chase her back in with a spray bottle. Should I let her out ever once in a while? I have a harness and leash from my Guinea pigs that fits her and I could take her out like that. But I'm scared shell run off. Plus there allege a lot of ferals(I live on a farm in town)
