Nope. Not agreeing with that in the slightest. My then-stepmother found a tiny kitten in a box behind the grocery store circa 1990 and brought it home because, well, you can't just leave a tiny kitten out in the elements to die. She already had one cat, but y'know. At the time, the new arrival was so freaked out and skittish that nobody could really approach it without it screaming and clawing at you. We figured it was shell-shocked so when it retreated under the bed in the master bedroom and refused to come out, nobody forced the issue. My stepmother put out a dish of food and bowl of water and let it be.
Fast forward 8 years later and the darn thing was still under the bed, and only came out like a ninja assassin skulking through enemy territory to eat its food and drink its water, and scratch and hiss at the other cats (there were 2 more by that point) if they got too close while it was eating. Oh, and occasionally it would attack your feet if you got too close to the fringe of the bedspread and it felt threatened. Maybe this kind of behavior is at least sort of cute when they're kittens and small, but by the second year after its rescue we had all simply written it off as crazy and irreparably broken. Rather than taking it with her when they divorced, my stepmother turned it over to a shelter because it was too much to handle.
Sometimes found cats (or dogs) were lost for a reason, as sad as that is.
