Initially, the two attempted to train Tigger to return to his family at night, but they ultimately gave up and decided to let Tigger sleep wherever he pleased. They are always listening for Tigger's meow, even when the door is locked, to be let in when he arrives.
"His parents have stated that Tig is true to himself and has chosen us," Sanders added. "They've stated that they're just glad he's warm and secure and isn't out on the streets."
The couple has no idea why Tigger has picked them and continues to sneak home for nights and family events, but they are ecstatic. They adore Tigger to the point where he's practically become a member of their family, and Tigger wouldn't have it any other way.
