BRENTWOOD (CBS SF) — A woman and son who visited an East Bay fire station to report a cat inside their vehicle’s engine compartment were told they were quite mistaken .. it was actually five cats.

The East Contra Costa Fire Protection District said in a Facebook post the mom and child arrived at Station 52 on John Muir Parkway, in Brentwood to report a cat was somewhere under the hood of their car. Firefighters couldn’t find it right away, and then were dispatched to two 911 calls in a row.

“An interesting fact we found out was that orange tabby cats are almost always males,” the Facebook post said. “80% of orange tabby’s tend to be males. Out of these three, all were males. Thanks to Officer Sutton for the tidbit of information.”
