An indoor cat wouldn’t stand a chance.

Curious by what you mean about struggling. Not trying to be simply contrary.

My (then) 16 month old, seven pounds wet with rocks in her pockets indoor cat escaped in 2018 and lived wild in rural Maine for 18 months before being trapped and returned to us (thanks to microchipping). She was 9 miles from home and had a broken paw (something fell on it and crushed her toes), but was otherwise healthy and in good spirits.

I tend to agree that a feral has an advantage based on common sense, but also that my tamed feral is a beast when he fights.
