My dad over the years has adopted several strays as his garrage cats. Basically he just leaves cat food out while he's working and ocasionally random cats swing by for a snack. Eventually some of those cats get comfortable around him and learn that if they come when he calls them in at night then they get the good wet food and get to sleep in the climate controlled garrage.
What I'm saying is that sprocket is 100% cheating on you with a random mechanic and has also become someones garrage cat.
