Meet Wasabi and Ebi,
Born in July 8, 2026, these orange kittens are playful, curious, and remarkably gentle. Raised together in a loving foster home, they’ve grown up as a true team and would love to stay that way.

Wasabi (the adventurous brother) is a fearless little explorer. He’s usually the first to check out a new toy, dart into a room, or see what you’re doing. If you enjoy a kitten who brings lively curiosity and energy to every corner of the house, Wasabi is your guy.

Adopt Lexi & Poppy! Lexi and Poppy have two different mamas, but one shared love of companionship. The first day they met, they bonded and became instant besties, with endless purrs.

Lexi (female, long-haired black with a bit of smoky grey, born 8/9/26) went for a few wild rides underneath vehicles after seeking warmth on a couple of cold nights. She was miraculously unharmed but slightly terrified, and she quickly transformed into a social, loving kitten with silky soft fur.

Adopt Squeakie (m) and Sweetie (f!) Born on 6/20/26, Squeakie and Sweetie are ready for a cuddle puddle with you!

They were found in a Walnut Creek backyard, where their mama brought them each day to be fed, and they would watch through the glass door asking for the soft inside life.

Sweetie is a true cat's cat. She loves lounging in the window, quietly observing her kingdom. She likes you to come to her, and when you ask for snuggles, she happily gives them.

Meet Kimura (Kimmie for short) and Leo, 5 month old kitten brother and sister, and the perfect combination of temperaments and personality. These two came from a hoarding/ neglect situation and were starved and sick upon intake. Luckily, these two are resilient and pulled through though not all of their siblings were as fortunate. Due to all of the early medical intervention and care, they have grown into quite the tolerant, gentle, and loving duo making them suitable for respectful children.
Kimura (Female, Black nose) - Bold, confident, and rambunctious, she is the first one to show up to the party and the last one to leave. She loves to play, gets along with everyone, seems to like being held and pet, takes medication well, and allows for nail trimming without incident. While she is affectionate and sweet, her number one priority right now is play and she goes all out with a wand and mice (her favorite). She is full of spunk and character. Also, she has the most beautiful multicolor eyes!
Leo (Male, White face) - Gentle, calm, and serene, there is something about this little boy that is hard to put into words. While he loves to play, he also has a slow paced, observant nature that somehow exudes peace and tranquility, reminding his humans to slow down and breathe. When he wants affection, he never imposes or asserts, but rather quietly and patiently waits. He will gently lean into your hand and paw for you in the air without touching you signaling for more love. You will find him curled up around the house in the most cozy of spots sleeping peacefully, though he is more than happy to be stirred for pets or treats. Along with his peaceful, tranquil vibe, he loves plants (primarily eating them) so he will need a home where he is kept safe from himself in that department.

Meet Ber & Bolo ( about 5 months old), two brothers who also happen to be besties. They came from a hoarding/ neglect situation and were starved and sick upon intake. Luckily, these two are resilient and pulled through though not all of their siblings were as fortunate. Due to all of the early medical intervention and care, they have grown into quite the tolerant, gentle, and loving duo making them suitable for gentle children.
Ber (all gray) - As sweet and loving as they come. He is a purr box and starts rumbling before you even begin touching him. He cuddles wonderfully and is the only of his kitten counterparts who prioritizes affection and cuddling over play (though he also loves to play).

Meet Triple Dipper and Baja Blast—two adorable brothers born on June 25, 2026!
These playful panthers are full of personality and twice the fun. Triple Dipper is a handsome medium-coated boy, while Baja Blast sports sleek, short hair. They’ve been lovingly raised in a foster home alongside two German Shepherds, who they absolutely adore. If you already have a dog, these two will likely be thrilled to welcome a couple of new canine best friends!

Please contact Lori to meet them! Whisker2love@gmail.com or text 209-996-8870
Meet Mama Pearl and her daughter Opal!
These two are about as sweet as they come and SUPER FRIENDLY. Affectionate, gentle, and incredibly friendly, they love people and are always happy to soak up some attention.
Pearl is a stunning girl with the softest, rabbit-like fur and an equally beautiful personality (about one year). She’s confident, gets along wonderfully with other cats, and seems to love everyone she meets. Little Opal is every bit as sweet and loving as her mama.
Opal lost an eye after being rescued from a dog attack, but it hasn’t slowed her down or changed her affectionate nature one bit.

Dinho and Mia are an adorable tuxedo pair of siblings. They look identical until you notice that Dinho has the cutest one spot on his nose.

Just hand her one toy and she's good to go. And her absolute weakness, temptation treats. If you've got those, you've got her heart.
