Kiwi 2, an adult female cat up for adoption

Hi, I’m Kiwi! I’m a 5-year-old girl looking for a new family because sadly, my owner is moving and can’t take me along.

I’m a loving, cuddly girl who loves being close to my person. Once I choose you, I’ll be your little shadow, snuggling beside you at night and filling your days with love. I also have a playful side and love to hunt! I can tolerate other cats and get along with small dogs, but I’d truly thrive as your one and only. All I want is a person to call my own and a forever home where I’ll always be loved. Could you be my second chance?

Hey there! I’m Mariel Hemingway! I’m a fun-loving girl with extra toes (yep, I’m a polydactyl!), and I’m always ready for my next adventure! I love jumping, playing, and being a little silly. I may be a bit clumsy, but that just makes me extra cute! I sometimes get carried away with my play bites, so having another kitty around to help me learn good kitty manners would be awesome! Once I’ve gotten all my zoomies out, I’m all about the cuddles. I love sleeping beside my humans and snuggling as close as possible. Could you be the one to give this extra-toed girl her forever home?

Willow loves to hang on your arm and play with her siblings all day long. She's a hit at adoptions with her siblings and she is so super sweet. She loves to be doted on and is just a love to have around.

I may have a tiny little body, but don’t let that fool you—I have a HUGE personality! I’m a Bengal girl who was rescued from a retiring breeder situation, and I’m learning more every day what it means to be a spoiled, loved house kitty.

Why adopt an adult cat in Rancho Cucamonga

An adult cat's personality is fully formed, so the rescue can tell you how they are with people, other pets and busy households. Many have lived in foster homes and are used to family life.

Grown cats are calmer and need less supervision than kittens, which suits people who work long hours or have young children.
