AVENAL, Calif. -- Administrators at Avenal State Prison said they will have to kill more than 100 cats that have sneaked in and reproduced inside the facility.
The felines have become a health nuisance for the prison. The state has cited the prison for unsafe working conditions because of cat urine and feces.
Prison officials said they do not know how the animals got in.
Over the weekend, volunteers removed about 50 cats, taking most to a Central Valley ranch. Volunteers spayed and neutered and the animals, and gave some veterinary care.
There are still about 100 more roaming the facility, prison officials said.
Prison workers are trying to trap the animals.
