The Eagle newspaper reported Tuesday that Veronica Rodriguez was shocked in early May when the big snake turned up in her bathroom.
Police believe the African python slipped into the house when Rodriguez left the back door open after bathing her three household guinea pigs and putting the critters in outdoor pens.
Rodriguez says she heard strange noises, returned to the bathroom and discovered the snake crawling into the tub. She called 911.
College Station police and animal control officers removed the snake, using a city trash can as a temporary receptacle for the reptile.
No guinea pigs were harmed.
