People often drop their pets in the wild, that's how once we found something like this... ...we was thinking it's gosling, cuz of typical noise (was holding our own farm in "Smallville" and thought one of our goslings lost in grass). He was in terrible health state, hardly could meow. Months later we got it, that kitty never getting older neither grows. After few years guesting in my house, he just disappeared without trace.
