NOVATO, Calif. (AP) — The San Francisco Chronicle (http://bit.ly/1Bm6coH ) reports that someone has dropped off more than 100 tuxedo cats, which are named for their distinctive black and white markings, at an animal shelter.

Marin Humane Society spokeswoman Lisa Bloch says that on Monday, a car pulled up to the Marin Humane Society in Novato, leaving behind three boxes.

Bloch tells the newspaper that inside were 24 tuxedo cats. She says it was the fourth such occurrence in the last 18 months.

The newspaper reports that all the cats, which range in age from kitten to full-grown, appeared to be in good health, with no fleas or diseases.

The person who's responsible for leaving the cats has been caught on surveillance tape — and Bloch tells the newspaper that it appears to be the same person every time. The shelter wants to offer the person information about getting pets fixed.
