6. Mariel Hemingway

Young (3 months 3 days) · Female · Calico / Domestic Short Hair / Mixed (short coat) · 13 mi from Ontario

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?

Young (7 months) · Female · Domestic Medium Hair (medium coat) · 23 mi from Ontario

Willow was born into a colony that was breeding out of control. The "owners" didn't realize how big of a problem not getting a few cats fixed could be or how fast they can multiply.

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.

9. Princess Polly Pocket

Adult (2 years 1 month) · Female · Tabby (medium coat) · 23 mi from Ontario

** COURTESY POST FOR INDEPENDENT ADOPTER:

Princess Polly has already beaten the odds, and now she's ready for the happy ending she deserves.

Princess Polly is a petite, gentle girl. When she first appeared, she was severely emaciated, with her bones visibly protruding from starvation. We weren't sure she would survive, but this little fighter proved just how resilient she is. Thanks to lots of love, care, and good food, Princess Polly has made an incredible recovery and is now ready to find her forever home.

Read more about Princess Polly Pocket

Polly is the definition of a sweetheart. She absolutely adores wet food and never turns down mealtime. She's a quiet, easygoing couch potato who would much rather curl up beside you than cause any trouble. The moment you start petting her, she melts into a purring puddle of happiness.

One of Polly's favorite things in the world is being brushed. She could happily sit for hours soaking up the attention and affection. Her calm, loving personality makes her a wonderful companion for anyone looking for a gentle and devoted feline friend.

Princess Polly is deeply bonded with her friend Jebediah and takes great comfort in having another cat around. She would thrive in a home with Jebediah or with another friendly feline companion who can help her feel safe and loved.

After everything she's been through, Princess Polly deserves a life filled with soft couches, full bowls, gentle brushes, and endless love. If you're looking for a sweet, quiet companion with a heart as beautiful as her story, Princess Polly may be the perfect match.

11. Marmont

Adult (1 year 1 month) · Male · Chartreux (short coat) · 23 mi from Ontario

Meet Marmont, a breathtaking Chartreux mix with a heart as grand as his handsome frame. On the 4th of July, Marmont’s life changed forever when he was left abandoned in the bushes alongside an empty carrier and a few empty cat food cans. Terrified, unfixed, and severely underweight, this resilient boy mustered up all his courage and ran straight out of the bushes looking for human help. Since that fateful day, Marmont has been steadily gaining weight, gaining confidence, and discovering what it feels like to be truly safe and cherished.

Read more about Marmont

True to his Chartreux heritage, Marmont is an incredibly loyal, devoted companion who thrives on human connection. While Chartreux cats are famously known for their calm and gentle natures, Marmont adds his own charming twist: he is quite the vocal talker! He will happily follow you from room to room, narrating his day and ensuring he’s always right by your side. Given his background of starvation, it is no surprise that Marmont absolutely adores food and treats, though he remains wonderfully sweet and not food-aggressive in the slightest.

Marmont gets along well with other polite feline friends, but what he wants most in this world is his person. He craves human affection, loves interactive play, adores lounging on tall cat trees, and could spend hours blissfully sunbathing in a warm window. At night, he wants nothing more than to curl up and sleep right next to you. Marmont is still filling out his lush grey coat and sturdy frame, and he is going to be a wonderfully large, impressive boy once fully restored to health. We may not know the hardship of his past, but with your help, his future will be endlessly bright. Reach out to adopt Marmont today and give this deserving boy the forever promise that he will never be abandoned again.

I may be tiny, but I have a BIG personality! I’m playful, curious, and love exploring, chasing toys, and seeing what my people are up to. I’m also quite the little chatterbox and love having conversations with my humans! I’m a total purr machine who loves pets, attention, and being part of the family. I’m also a social girl and don’t do well being alone, so I need a home with at least one other friendly, playful cat to keep me company. I’ve been around children and I’m good with both small and large dogs. I just need a slow introduction to my new furry friends so we can get comfortable with each other. I have so much love and personality to share, and I can’t wait to find my forever family. Could it be you?

29. Rebel

Young (7 months) · Male · Tabby (short coat) · 23 mi from Ontario

Rebel is a rambunctious little guy who was rescued from the streets of Fontana after being chased by a dog. He loves hard, plays hard and sleeps hard. He will need a buddy who can keep up with his energy level who is even-keel and up for playtime. He likes to snuggle and curl up in your lap when he's not doing zoomies or at the top of his cat tree surveying the dangers that lurk below in his play world.

Adopting a cat in Ontario

Most rescues ask you to fill in an application, meet the cat, and pay an adoption fee that usually covers spaying or neutering, vaccinations and a microchip. Many are foster-based, so you'll often meet your cat in a volunteer's home rather than a shelter.

Senior cats are often the calmest companions and the slowest to find homes. If you'd like a settled, affectionate cat, ask the rescues about their older residents.

Kittens go quickly, especially in spring and summer. If you've fallen for one, contact the rescue soon, and think about adopting two: young cats keep each other company and out of mischief.
