I do have to say though - patios, catios or leashes are the best way. If your cat is supervised, don't go to the bathroom or answer a phone while supervising. And, don't forget: If your cat bolts away from you, you won't be able to catch her if she 'do'.Disclaimer: I'd never let a cat roam in a city. The cat we have at home is allowed in the backyard under supervision.
