A friend of mine "adopted" a feral kitten from a garbage can. She opened the lid, saw him, picked him up and would up taking him home. He's the most affectionate and stupid creature I have ever met - he makes a ginger cat look like a genius. He forgets which window he left from (she leaves an open window for him) and sits at the front door meowing. He has walked off the edge of tables and was genuinely surprised to be on the floor. He would try to play with his litter mates, who were still feral, and be confused as to why they would run away from him (he's a big tomcat). At the end of the day, the cat has a loving home, and my friend has a sweet, albeit derpy, tuxedo companion.

Perhaps this mouser is a distant cousin of his Canadian counterpart.
