<human>: Give me a shortened version of the text

My wife's sister lives their parents and has a ball python as a pet, about 1 year old, and about 16 inches long which she raised nearly from birth.  The lid on the cage was a stack of books, evidently not good enough.  The snake escaped and nobody has seen it for 4 days now.  My mother in-law is frightened to go to sleep in case it crawls into bed with them at night.

The house has two hunting-savvy cats and one kind of stupid/socially damaged husky whom we watched eat a whole live rat once, but no snake corpse or evidence of attack has been found.  It also has forced air heating with ducts at floor level.  The house is structurally sound but fairly old and a snake may be able to find its way outside.

So how do I catch this snake? where are common places for them to hide?  is there a bait and live trap I can get somewhere?
<bot>: Snake in the house, need it caught alive, risk of semi-retarded dog eating it, time is a factor.
