LOST PawBoost ID: 72550964


Buena Park, CA 90620

He is 3-years-old now and has been missing since September 6th, 2025 out of Buena Park, CA in the General tract neighborhood near Valley View and La Palma Avenues. 3-year-old neutered male tabby cat. His front right leg is all white. His left front leg has all markings and a white paw. MAIN REWARD is for a safe return to owner! Please do not chase or try to capture. Just take a picture and send it to with a location. $50 cash reward offered if it is confirmed to be our cat. If you can't take a picture please report the sighting anyhow. Any positive leads can lead to a substantial reward! He could be in the General tract (by La Palma Ave between Valley View and Knott Aves) or surrounding tracts or areas/cities. Please inform any feeders/rescues or people who aren't on social media! Thank you for your help! We understand that after this length of time there is a possibility that someone took him in and has claimed ownership. Please do not disregard our plea to know his whereabouts. If you have him please do not hide this from us. We are looking for closure and although our goal is to bring him home we need to ensure he is ok and know where is he and what happened to him. There is a hefty reward for his safe return. We miss him terribly so please do the right thing and reach out to us and find it in your heart to return him. 🙏

Frequently Asked Questions

I lost my cat. What should I do?

Take advantage of online platforms – they help you get the word out, quickly and easily. You can report your lost cat 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 cat to our lost & found, and make a lost cat flyer – all for free.

Other sites that help you raise local awareness for your lost cat 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 cat'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!
