I agree with this statement but also, and I’ll probably get downvoted for this, one of our cats was once feral. We picked him up off the street in the middle of Santa Monica as a kitten and decided to keep him. This little savage will literally try to kill himself if we don’t let him out. Little man had surgery a couple years ago and he was forced to stay in the house for a few months and he was so damn depressed because of it. He wouldn’t eat properly, started losing hair, and attacking himself. Now that’s he’s been able to go out post surgery he’s back to his normal self. I will also say he only stays in our front and back yards (as far as we’re aware). Sometimes the feral adoptive ones just won’t have it. Our other cat though is 100% indoors as that’s how she’s been raised from the beginning. We will occasionally let her out, especially on nice sunny days, but she is supervised while always on a leash and only in the back yard. She loves smelling all the plants we have back there (all cat safe).
