We took the other cat, because we had two cats at that time (the other cat was also black, but chubby and female), and by the time we went back to the other skinny, black male cat, he disappeared
Later (shortly after moving to the other house) the female cat also disappeared.
Since then, we had only a black and white cat (in the same house), who got hit by a car.
Maybe the other, previous cats also got hit by cars.
But we do not know.
I have not had cats since then.
Nowadays I live with a female Harris's hawk.
