MISSING CAT!! o Neighbors, My cat, Smokey-Sebastian, left on April 2nd, 2026 around 6:00pm and never returned. This is very unlike him. Since I rescued him almost 4 years ago, he has never spent a night outside. If you live in the Castro Valley area, I ask that you please check your sheds, grges, crawl spaces — anywhere he could be trapped. He is very friendly and may approach if you crouch down and hold out your hand for pets. He went missing from Walnut Rd, but could be making his way to our old hse on Nunes Ave. I am extremely worried about him. He has been missing for 3 weeks now and I miss him so much. Please help me find my sweet boy and bring him !!

(Sorry I accidentally posted and deleted a few comments made an error). *** TONIGHT *** Go out and CALL For kitty in a very calm, NORMAL voice, with zero` stress in your voice, and if your kitty likes the sound of crinkling a treat bag or opening a can of food then try that...call for your sweet kitty for 30 minutes straight - listen for faint meows nearby in case kitty is stuck at a neighbors (many cats will NOT meow for fear of predators) Walk around VERY SLOWLY calling for kitty. Be patient - cats accidentally get locked inside garages and sheds and storage areas when neighbors leave town. *** IMPORTANT *** Set your alarm for 3am to walk around very very slowly and call for kitty calmly over and over. Call for kitty early AM before the sun rises and at at night. —- 💜🙏 Dear guardian. I'm so sorry your sweet Indoor/Outdoor kitty is missing. Kitty could be STUCK / TRAPPED at a neighbor’s unable to get back (OR GOT spooked and is hiding nearby) and why you must take action in several ways in order to cover ALL possibilities - ESPECIALLY in person – with the neighbors on the block to start. 🐱 Taking ACTION IN PERSON is CRITICAL: 🐱 Leave a WAY BACK INSIDE for kitty to sneak inside in case kitty is now stuck in a garage and gets released… 💥TONIGHT - CALL FOR KITTY CALMLY and sweetly, with ZERO stress in your voice. Cats are most active at night (KITTY could have been spooked and is now hiding in survival mode OR got STUCK in the process of hiding) Set your alarm for 12AM and 3AM and WALK AROUND VERY SLOWLY calling for kitty in your NORMAL, CALM voice...shake/crinkle the treat bag or shake kitty’s favorite noisy toy. Many cats come out of hiding during these late hours(or you can hear meows if trapped in your next door neighbors garage or backyard for example. Many cats will Not meow if stuck. Be Patient. Scared cats are the best hiders. 🐱🐱ASK NEIGHBORS to check their RING CAMERA and to add a missing cat alert. ASK neighbors to partially open garages and sheds and crawl spaces for a few hours - any place they opened and closed since your cat's been missing. 🐱 GAIN ACCESS TO YOUR NEIGHBORS YARDS: Get permission for YOU to check their yards physically -.explain kitty will hide from strangers and it's best for you to check anywhere kitty could be hiding, under a crawl space or deck (Use a flashlight to catch the reflection of kitty’s eyes. They are silent hiders. Sometimes you have to check more than ONCE in the same yard...https://drive.google.com/.../10I.../view... 🐱 Neighbors will NOT do anything if they see a cat outside, UNLESS they know your cat is missing and have your number! 🐱 PRINT 150+ FLYERS ASAP to give your neighbors door to door and also post up around your block + neighborhood. KNOCK ON YOUR NEIGHBORS DOORS starting with your block. POST UP FLYERS on both sides of streetlights, place inside ‘clear sheet protectors’ with the opening facing DOWN so weather doesn’t ruin them. Google “Protective Sheet Covers”. You can purchase on amazon or any office supply. To save time place ONLINE order of FLYERS at your nearest FEDEX PRINT STORE for pick up, Even if they’re closed. Call once open , asking if they can PRINT right away. They will usually expedite the order. NOTE: Fedex also sells sheet protectors, packing tape + duct tape for posting Flyers on lampposts and blue ‘painters tape’ for taping flyers onto front doors or ON Mailboxes without causing any damage. 🐱Download a Flyer ‘template’ from www HappyCatLady com. Offer a reward for a PHOTO of your kitty and call and not to approach kitty.. 🐱 Spreading the word IN PERSON is Critical in spotting kitty. MOST who are on Facebook and Nextdoor.com don’t get notifications so you MUST go door to door in person, circle your block and across the street to start - make sure every neighbor knows about kitty . Ask neighbors to take a photo and call if they see kitty and NOT to approach. ASK neighbors to check their yards / garages /sheds, roofs, storage units, crawl spaces. Kitty could be trapped (happens all the time!) The goal is to TALK to as many neighbors IN PERSON as possible. Talking to neighbors increases the chances of your cat being spotted or discovered Stuck, talking engages people to care and to actively search 🐱 PRINT OUT A GOOGLE MAP OF YOUR BLOCK with address #s showing and take notes which neighbors were home you spoke to and which homes to try again later if no one answers. Keep trying to catch neighbors in person later that day and the next day/s. Talk to residence around your block and across the street. Without a printed map, it's easy to get mixed up when you're stressing out.(see example ). https://drive.google.com/.../1ZDSAf2ky52.../view… 🐱 APARTMENT BUILDINGS: For distributing flyers, I ring bells and talk to folks and/or at least get inside the building so I can leave a flyer In front of every door step. If not an option then neatly tape flyers down the side of EACH mail box! You want to cover all possibilities. MAILBOXES EXAMPLE _ FLYERING https://drive.google.com/.../1pQTHFCYD.../view… 💥 IMPORTANT 💥If your cat accidentally got out into a NEW, FOREIGN LOCATION, THEN PLACE A CAMERA (motion activated) AIMED at WET food bowl and water (before each SUNSET) you leave by the open escape door or just inside the garage door left open 5” (if kitty got out from the front and you have a garage) you can't believe how many times a cat will return home - eat - but has no way of getting back inside OR kitty just WILL NOT go back inside the house because kitty is spooked , in survival mode. WHen you observe kitty on camera coming to the food BUT continuing to HIDE FROM YOU, THEN RENT OR BORROW A HUMANE TRAP (raccoons LOVE dry cat food so only offer WET). NOTE: You must monitor the trap every second it is set or you could cause harm to your cat. 💥💥 CAMERA: Mini Blink WIFI camera $35 : https://a.co/ihc7BSy OR Blink Waterproof WIRELESS camera $64: https://a.co/d/cDeKLXz IF NO WIFI: Wildlife/Trail camera (battery operated) check footage manually daily https://a.co/d/a4Rqqdp, comes with 8 AA lithium batteries (buy extra) + Micro SD Memory Card - : https://a.co/d/44AXvel 🐱 DON’T GIVE UP🙏 Every day I get texts from cat guardians whose cats were stuck in a shed, under a neighbor’s garage, on a rooftop, inside a storage space or that a neighbor heard a meow in their yard at night. Each cat is different. Return to those addresses if no one was home when you knocked. Keep track on a printed map which neighbors weren’t home so you remember to return - kitty COULD have gotten trapped on their residence,before leaving town so talking to every neighbor is KEY.. Sometimes you have to check the same spot 3 times! → https://drive.google.com/file/d/10I_aHnjJ9rX6rYbGi6v7AWUTJVqggIxD/view?usp=sharing ONLINE: please do not rely on online 🐯 SEE BELOW example of taking notes on map as I went door to door. F = flyered (not home) Added names I spoke to in person - the goal is to talk to everyone to best engage neighbors - ask them to check RING cameras, search garage, storage, sheds and to CALL if think they see kitty (and take a photo) Keeping track on a map is a HUGE HELP - I return days later to remind folks to keep looking! 🐱LINK TO PDF OF LOST CAT FLYER / GOOGLE MAP GRAPHIC EXAMPLE: https://drive.google.com/file/d/1cYfhp2o-m2C_OKPvdEriHZxYscDmeL5U/view?usp=sharing

He is not making his way to your old home!! This is a MYTH . he is likely STUCK/ TRAPPED at a neighbors - your neighbors aren't on pawboost. Talk to neighbors during the day adn search for him at night. You must walk around at night calling for him calmly as you circle your block and go 1 block out in all directions - sometimes they meow sometimes they won't. FLYER your neighbors - knock on doors asking them to PARTIALLY open bats and sheds and crawl spaces for 3 hours allowing him time to escape and come home... 🚨🚨🚨WARNING🚨🚨🚨 SCAMMERS will claim they found your cat! Or will tell you about a (FAKE) INSTAGRAM Pet recovery service they used - OR WILL SHOW YOU an AI (FAKE) photo of your cat - these are SCAMMERS!!! SCAMMERS will text you saying they’re affiliated with Pawboost or an ANIMAL SHELTER and that they HAVE YOUR CAT and that YOU need to PROVE who you are by giving other phone numbers, your email, verifying google codes etc or to send money to get your cat from the shelter. These are all SCAMMERS! THEY WON'T Send you a PHOTO of your cat (they'll make up any excuse) OR THEY'LL SEND a PHOTO of a similar cat OR AN AI FAKE PHOTO - or a blurry video - but it’s not your cat! Look closely. Google the photo they send it could be a photo they stole from the internet. Please know that If your actual neighbor sees or has your cat they will give you information freely (and will post a PHOTO on your listing and not make you ‘send a code or personal information or money. 🚨🚨🚨There’s a NEW SCAM they will call you saying they are animal care and control and that your cat was brought in but got hit by a car and needs an operating then they will ask you for payment - THIS IS A SCAM!!!! Animal care and control would NEVER ask for money 🚨🚨🚨 ASK TO FACETIME ANYONE WHO CLAIMS TO HAVE YOUR CAT (TO PROVE THEY HAVE YOUR CAT) AND THEY ARE ASKING YOU FOR A $ REWARD. SCAMMERS are the ONLY PEOPLE WHO ASK FOR A REWARD. 🚨🚨🚨There’s a NEW SCAM on Facebook the scammer will say something like ‘my husband found your cat or your cat was hit by a car please message me your phone number and send $ “ meaning they want you to message them from your Facebook messenger your phone number! 🚨🚨🚨The Facebook SCAMMER will tell you to look up a lost cat search team they used on Instagram or another platform saying their cat was found within hours -it’s a total SCAM. LOOK AT THEIR FACEBOOK PROFILE - you may see many (PAID) followers but they are not following anyone, The profile will have a few photos only, usually just selfies and the profile was created not long ago. You will see no posts / conversations with friends , I report the account to Facebook Scammers are heartless

Please check the neighbor's bats and garages, kitty might have gotten locked. Check both sides of the block. If you can't go in, call the cat's name. Check places that your cat might hide if injured. Call shelters, keep calling - go in in person. If you have shops, libraries, and gas stations nearby... put up flyers, and check-in with people at the counter. Put flyers up around the neighborhood, and talk with your neighbors. Good luck!
