A seven-foot boa constrictor has slithered away from the home of the Delaware County veterinarian who owns it.
Police in Swarthmore and the snake's owner, David Spiegel, said the snake likely doesn't pose a risk to humans or even most pets -- though it may well attack ground moles, frogs or birds.
Spiegel said he typically lets the snake sun itself in his yard, but on Monday the snake was gone when he returned to check on it.
Swarthmore police Chief Brian Craig said residents have been alerted out of "an abundance of caution."
Spiegel said the snake, named 'Snakey' is "friendly" with other pets as it has been raised with their children, two cats, and a tiny dog.
The snake has slipped away from home at least once before and been returned.
