At first, they thought maybe it was a catbird.
But a search of the trees around the Oak Grove trailer park in Hatfield, Montgomery County, didn't turn up a feathered source of the mysterious meows.
As they drove around town, Wilmer and Edith Kramer began putting two and two together.
It sounded like a kitten.
Somewhere inside their Chevy Suburban.
They searched the entire vehicle and even crawled underneath, but couldn't find a stowaway.
``So we put tuna fish out underneath the car one evening and figured if the cat was underneath there, it may come out to eat,'' said Edith Kramer. ``The tuna fish was gone the next day, but the cat was not.''
