My cats were all indoor cats in NYC. No choice. But one old guy got out every time he could. It broke his heart not to be able to roam.
Now mine all live indoors but wander at will. I love to watch them prowling and playing with leaves. Freddie of course kills whatever he can corner. Lizzie sits in the driveway and suns herself like a nosy old lady. They don't go far but Freddie does crosas the street. Still I wouldn't deprive him of his outdoor life.

Poor little Buttje. Sorry you lost him, lead.
