Chance - REWARD Male Cat

LOST PawBoost ID: 72007457


Orange County, CA 92606

REWARD offered for safe return to owner. $50 REWARD for a confirmed clear photo or footage with date and location. Please note his front right leg is all white so be on the look out for that. 2-year-old neutered male gray/brown tabby with black spots/stripes, white nose/mouth/chest/lower neck/various spots on legs. Do not try to capture unless you can safely lure and secure him. Just take a picture and send it ASAP. It would help to zoom in on the cat so we can see distinct markings and zoom out on location so it will be easy to locate. If you can't take a picture please report the sighting anyway. Any information helps and positive leads could lead to a reward. He went missing Saturday September 6th at 4pm. We think he may be in the area, surrounding tracts, cities, or anywhere in the region because we can't rule out that he was displaced. Please text if you see him! Please check your sheds/grge/attic or anywhere small animals can hide or be trapped and please inform any feeders or neighbors who are not on social media! Thank you!

Grimm Female Cat

LOST PawBoost ID: 72981158


Garden Grove, CA 92840

Grimm was last seen June 7th at 8:30 pm on security camera sneaking out behing my FIL. She is a 9 yr old FemaleTortie cat with medium fur. Her nose is half orange and half brown colored. And her fur pattern on her face makes her look like she is serious. At the time she had a seresto flea collar on when she snuck out behind my FIL when he went out the back door without anyone knowing while we were on vacay. Grimm loves catnip, and "helping" make the bed and drinking water from the faucets. She is bonded to her sister/littermate and my youngest kid. She is greatly missed by everyone, but especially my child, who has had her for most of their life and her sister. Her poor sister has been crying at all the windows looking for her for weeks now.

Frequently Asked Questions

I lost my pet. What should I do?

Take advantage of online platforms – they help you get the word out, quickly and easily. You can report your lost pet to PawBoost in no time flat. We'll send an email alert to our local members, post to the PawBoost-powered Facebook page for your area, add your pet to our lost & found, and make a lost pet flyer – all for free.

Other sites that help you raise local awareness for your lost pet with minimal time and effort are Nextdoor.com – a PawBoost partner – and Craigslist. Both of these sites have very active lost & found sections mainly used for lost pets. We highly recommend you use these resources in addition to PawBoost!

Visit your local shelters and animal control agencies in person. Details can get lost in translation over the phone and that might lead to missed connection.

If chipped, make sure your pet's microchip is registered and up to date. If you don't know your pet's chip manufacturer or number, your vet should be able to help locate this information.

Put up flyers and tell your neighbors to be on the lookout. The more you engage the Costa Mesa community, the better your chances of a happy reunion!
