LOST PawBoost ID: 73276866


La Verne, CA 91750

Gray and white cat, 14 years old, petite, pink birthday collar with phone number. Her name is Anabel. Anabel is 14 years old, gray and white, very friendly, and loves people. She also takes , which makes finding her even more important. She is microchipped and was wearing a collar similar to the one pictured in the photo I posted. If you see a gray and white cat wearing a collar that looks like hers, please let me know. My number is on her collar. I know there are coyotes in the area, and I understand the risks.Please spare me the lectures or criticism right now. I’m not looking for judgment...I’m just trying to find my cat. ❤️ If you live near Fordland & Payson, please check your yards, garages, sheds, bushes, porches, and anywhere she might be hiding. If you see her, please message me, even if you're not completely sure it's her. 📸 I’m posting pictures of Anabel and her collar below. 🙏 Please share this post, especially with anyone who lives in the San Dimas area. Someone may have seen her and not realize she is missing. Thank you so much for keeping an eye out and helping me bring my sweet Anabel home. ❤️🐾

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 Ontario community, the better your chances of a happy reunion!
