I'm late! But chip for sure! Recently got my 15 year old diabetic cat back in an hour when he broke free..(someone screwed up..) he was picked up by animal control because a neighbor thought someone dumped a sick cat..() Our police Dept is Our Animal control..I got a call that George was in lockup and needed a ride home! I was sooo relieved to see that scrawny old Dude! If he wouldn't have been chipped..I shudder to think what would've happened. later that evening..when I went online, I had also received an email from HomeAgain (the chip company) telling me George was safe and waiting for me at Monrovia Police Dept! get a chip...yesterday
