Atlas Male Cat

LOST PawBoost ID: 73092243


Oakland, CA 94602

ATLAS is a 7 year old Brown/tan/white (some silver patches) American Shorthair Tabby Cat. He has a marbled pattern. He is indoor/limited-access outdoor cat who is my sweet kitty that disappeared at 10pm on 7/2/26. He typically does not go out at night and I'm worried that he was scared by the fireworks and ran away. He had a tracking collar on and a blue collar with an orange/gold name tag. The tracker malfunctioned :-(. Both breakaway collars so he might not have them on. He responds to treats and calling his name. Please call me if you see my cat!!

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 Castro Valley community, the better your chances of a happy reunion!
