Guards thought there was something suspicious about a little white cat slipping through a prison gate in northeastern Brazil.
A prison official said when they caught the animal, they found a cellphone, drills, small saws and other contraband taped to its body.
Alagoas state prisons spokeswoman Cinthya Moreno said the cat was caught New Year's Eve at the medium-security prison in the city of Arapiraca.
The O Estado de Sao Paulo newspaper reported that all of the prison's 263 inmates were suspects in the smuggling attempt.
But the investigation could take a while. "It will be hard to discover who is responsible since the cat does not speak," a prison spokesman was quoted as saying.
