Two of my girls are long haired show kitties so I don't use the collar since it can wear on the hair. But they're chipped. Even my elder rescue is chipped to be safe; her collar came off when she started fighting it a year ago (she'd had collars for 15 years).
I do know that two of the three are cuddle bugs and adore people so if they get out, the chips will get them home.
