Is this a smart of desperate cat? Or both?

My niece has door handles like that at her house and her Labrador Retriever has figured out how to get out a few times! luckily she lives in a quite neighborhood with little chance of her dog getting hit by a car. Still … it’s not good when pets get out unexpectedly is it?

Do you have a pet that’s figured out how to get out of the house through a door or window or perhaps out of it’s cage or crate?
