Lost Montara cat “Sammy” since Sat 19th

I am searching for my cat "Sammy" who has not been seen since Saturday night on the 19th.  He is white and brown Tabby and weighs 10 pounds with no collar or tags.  He is a friendly cat , but may be shy to strangers.  I live at 559 4th st. in Montara where he was last seen. If you have any information about him , please let me know as I am worried and hope for his safe return. Please call me @ 728-3388 Thank you, Calvin Maule
