Adult Cats for Adoption in Vallejo, CA: 30 Grown-Up Cats Looking for a Home

Contact Paola at paolacresti@gmail.com. Lucille is being fostered by Elizabeth in Contra Costa County, CA.

Aloisius is adorable and a total sweetheart, and he deserves his own loving indoor-only home. It is likely he would get along with children 8 years or older who are gentle and can move more slowly until he adjusts to his new family and environment.

Aloisius would do great in a home with another kitty, but probably not with dogs.

Aloisius was born in approximately September 2024. He is healthy, has been neutered, vaccinated, microchipped, and is ready for his forever home!

If you are looking for a great, gentle companion for yourself and maybe your cat, you cannot go wrong with this sweet, precious and very handsome boy!

This is a Courtesy Post, and Aloisius is with Angus & Friends Cat Rescue in Castro Valley, California. For more information, please text Deborah at 510-909-4961. Visit their website at https://angusandfriendscatrescue.com.

I'm curious, playful, and always ready for an adventure. I love chasing toy mice, pouncing on catnip toys, and investigating whatever catches my attention. When playtime is over, I'm happy to be picked up, cuddled, and showered with affection. I'm also a huge fan of treats, canned food, and especially Churu. Bring out a tube, and you'll have my full attention! Meet Jax! Hi! I'm Jax, and I like to take a little time to settle into new places. But give me some patience, and you'll discover what a sweet, affectionate boy I am! Once I'm comfortable, I'll happily soak up your attention, especially if chin scratches are involved. They're my favorite! I'm playful, curious, and love chasing toy mice, batting around catnip toys, and exploring my surroundings. I also enjoy being picked up and cuddled once I've gotten to know you. And just like my buddy Louie, I'm a big fan of treats and canned food. The way to my heart might just be through my tummy! Better Together! We're two sweet boys with lots of love, curiosity, and kitten energy to share. We love having each other around, and we're looking for a family who will welcome us both. With Louie and Jax, you'll get double the playtime, double the affection, and double the fun! A kind rescuer in Fresno gave us the chance to grow up safely indoors. Now we're ready for our next adventure—a forever home where we can stay together and be loved for the rest of our lives. Could you be our purrfect match? Rescued from Fresno. Fostered in San Francisco.

Sadie's sweet personality shows when she greets you for pets by lowering her chin and offering you the top of her head for a gentle pat. She is a curious girl following you around, always interested in what's going on. Sadie warms up slowly to new people but once she bonds, she will be your devoted companion. She gets along with another cat but she would also be fine as an only pet. Dogs and children are untested but would likely do best in a home that is quiet and calm. We estimate that Sadie was born around January 2020. Kitty Bio 3876MB-Sa.

If you're interested in adopting Sadie, or another of our cats, please fill out our adoption questionnaire at icraeastbay.org/adopt/how-to/.

Hazel is very sweet and learning that humans can be safe and kind. She has the cutest tail that sticks straight up like arrow!
Hudson and Hazel are deeply bonded. If you're looking for a super-friendly cuddle bug and sweet lady that is more independent this pair is your perfect match. They are about one year old.

Max is a playful boy who enjoys all types of toys, especially interactive wand toys. He also enjoys romping and wrestling with his brother, Melvin. He will do best in a home with another cat and Melvin would be an ideal match. An existing cat in your home should also work. Max is affectionate, calm, and easy-going. He would do well as a companion cat for a family with kids age 7 and older. He is also respectful of older cats. We estimate he was born in April 2026. Kitty Bio #3876MB-Ma. ▶️ scroll down for clip

And now, look at him! Leo has healed, his difficult days are behind him, and he is finally ready for the next chapter of his life. No more struggling with an injury. No more uncertainty about what tomorrow will bring. Just the promise of a safe home, a soft bed, full food bowls, and someone who will love him forever.

And trust me, I'm a professional hider! But with a little patience, some tasty treats, and gentle encouragement, I'll come out to say hello. Once I know I'm safe, my affectionate side really shines. I'm not a particularly high-energy kitty. I'd much rather curl up on your lap or settle into a cozy spot nearby and enjoy your company. I love rubbing my face against you, weaving around your legs, and soaking up all the pets I can get. When I'm feeling especially comfortable, I might even rub my face against yours and give you a few sweet kisses! I'll come when you call my name or pat your lap, too. Did I mention I'm a purring machine? I purr constantly when I'm happy, and I make the sweetest little trills and chirps to let you know how I'm feeling. My dream home would be a calm, quiet place where I can be your one and only kitty. I'd love a patient, understanding person who will give me the time I need to settle in. I also have some skin sensitivities, so I'm on a special novel protein diet that helps keep me comfortable and healthy. Concerned about me being FIV+? Don't be—there's lots of helpful information out there to put your mind at ease. I can live a long, healthy life, meow. If you'd like to learn more, here's a great resource from the Cornell University FIV Guide. I may take a little extra time to trust you, but once I do, you'll have a devoted, affectionate companion who will fill your days with purrs, chirps, and plenty of love.

We're also gentle with our teeth and claws, even when we're having fun. I'm Faith! I'm the fearless little shadow of the duo. I love following my humans around and being involved in whatever they're doing. New places can make me a little nervous at first, but it doesn't take me long to feel right at home. I'm curious, adventurous, and extremely food motivated. Let's just say there's not much I wouldn't do for a tasty treat! And I'm Mini Mia! I'm a little more reserved when meeting new people or exploring unfamiliar places, but once I feel comfortable, my sweet and playful personality shines through. I love climbing and exploring high places, and one of my favorite things to do is grab a toy mouse or wand toy and proudly carry it away. I was initially a little unsure about hands, but I've discovered that cuddles are pretty wonderful! I'm also the bigger and very patient sister, especially when Faith decides to flop right on top of me or steal a bite of my food. One of our favorite things is playing together. We love wrestling, chasing each other, and then settling down for a good grooming session. You'll often find us curled up in one adorable puddle of kitten sweetness, fast asleep. We really are the best of buddies! We're a bonded pair and must be adopted together. We bring out the best in each other, and with our affectionate personalities, playful spirits, and love of human companionship, we promise to bring twice the love and twice the fun to our forever home.

She enjoys short petting sessions and is beginning to seek out more attention, although she is not yet comfortable being picked up or sitting on a lap. We are continuing to work on that at her pace.
Karen uses the litter box reliably, eats well, and is unfazed by the resident cat’s occasional growling. She will hop onto tables or counters, but she gets down when corrected.
She is not a wildly playful cat, at least not during business hours. She has been seen chasing a ball around the room, loves a string-on-a-stick toy, and we suspect some of her more adventurous behavior happens after everyone else has gone to bed.
More recently, Karen has started spending time watching the world through the sliding glass doors, taking in all the neighborhood activity like the tiny judgmental homeowner she clearly believes herself to be.
Karen would likely do best in a calmer home with someone who is willing to let her continue building trust at her own pace. She is not a cat who wants to be scooped up and immediately smothered with affection, but she is absolutely showing us that she wants companionship and connection.
If you appreciate cats with boundaries, personality, excellent resting-bitch-face energy, and the potential to become a very loyal little shadow, Mrs. Karen Patricia Green may be your girl.
Please email beourpet@gmail.com with questions or to learn more about Karen.
GENERAL INFO:
Housebroken?: Yes
Non-Shedding?: No
Good with cats?: Yes, we think so
Good with dogs?: Unknown but likely fine with calm, cat-friendly dog and additional adjustment time
Qualifies for Seniors for Seniors?: yes
Umbrella of Hope does not have any strict rules on ages of children because all children are different, but our best approximation is that this animal would do best with children over the age of 10
Umbrella of Hope is an all-volunteer, donation-run, non-profit animal rescue based out of Pittsburg, CA that rescues animals from local shelters, places them in private foster homes, provides them with needed medical care and then finds them new homes.
Also, ask us about our seniors for seniors program, where we adopt animals 5 years or older to qualified homes with a $5 donation as an adoption fee. All animals are spayed/neutered, vaccinated, treated for parasites and given any additional treatments (dental work, bloodwork etc) as recommended by our vet.
Adoptions to veterans of the US Armed Services are ALWAYS free to thank you for your service.
We thank Well Pet Vet Clinic for providing most of our veterinary services and give a special thanks to volunteer photographers Tanya, Barbara, Kristy, Christine, Teressa and Natalie.

My Favorite Things:

Toy of Choice: The Cat Dancer! I will chase this as long and as fast as you can wave it around.
Nap Spot: Curled up on a soft blanket right on the couch.
Fun Quirk: I like to give the cutest little "trills" whenever I walk into a room to greet my humans!

Social Life: Jonesy has been a star in his foster home! He gets along wonderfully with other cats and is making great progress learning that strangers are just future friends who haven't handed over treats yet. He is already fully litter box trained and ready for his big adventure.

The Ideal Home: Jonesy would love a home where he gets plenty of playtime and affection. Because he still has that awesome 10-month-old kitten energy, he would thrive if adopted with a buddy or into a home that already has a playful feline friend to keep him company. He just needs a few days to adjust to his new environment, but he will reward your patience with a lifetime of love and silly antics.

We estimate he was born January 13, 2016. Kitty Bio #16566JBJo.

If you're interested in adopting Jonesy, or another of our cats, please fill out our adoption questionnaire at icraeastbay.org/adopt/how-to/.

He’ll nap nearby while you work, making him the perfect coworker for anyone working from home. During quiet evenings, he may settle beside you on the couch, gently lean against you, and reward you with the sweetest little purr.
Walk over to say hello while he’s lounging and you’ll almost always be greeted with that same loving purr. He has also been wonderfully gentle with the family’s 4-year-old and is comfortable when visitors come over — no disappearing under the bed when company arrives!
Don’t let his mellow personality fool you, though. Bring out the wand toy and Shakibby is ready to PLAY! He also enjoys putting on his leash and taking a little stroll around the backyard for some supervised outdoor time. The best part? He’s not demanding about either. If you’re busy, he’s perfectly content to relax nearby and keep you company.
Shakibby does not enjoy living with other cats, so he is looking for a home where he can be your one and only feline companion. In return, you’ll get a gentle, independent, sweet-natured boy with velvety-soft fur, that unforgettable little curled bobtail, and a peaceful presence that makes him so easy to love. ❤️
COURTESY POSTING: Shakibby is not currently in our rescue. If you are interested in adopting him, please fill out an adoption application and submit it to us. Once approved, we will forward your application to Shakibby’s owner, who will handle the next steps.
Sometimes the best companions aren’t the ones who demand your attention — they’re the ones quietly purring beside you, with an adorable little bobtail curled over their back. ❤️
