We have The Beans.... Mocha is the runner... she would like to "think" she can be an outdoor kitty but she is wrong (she tried once that's how I met my husband) Garbonzo on the other hand has absolutely no desire to leave the comfort of his home.. the two are different as nite and day... we are extremely careful when we open any and all outside doors, and we trained Louie from a pup to wait to go out until Both kitties were accounted for. It takes a lot of work but it's worth it. Right now we live in Very large home and have what we call the "buffer" zone... we enter through the backyard(fenced) into the garage, then into the house.
