They brought in a kitten who had been found in a puddle and watched her blossom alongside a feline friend who matched her spirit. FallonKelseyA tiny kitten named Fallon arrived at IndyHumane, along with her two siblings, after being found in a puddle on a back porch.Cold to the touch, the kittens were rushed into an incubator. Despite tireless efforts to save them all, Fallon became the lone survivor, using every ounce of strength she had to hold on.At just 110 grams and roughly four days old, Fallon, a polydactyl kitten, showed remarkable tenacity and hints of tortitude. KelseyKelsey, a foster volunteer with IndyHumane, noticed that determination from day one. Tiny as she was, Fallon had the heart of a fighter."She immediately warmed up and took to a bottle with ease. I knew pretty quickly that she was going to be just fine, as she was truly the easiest bottle feeder. Maybe holding the bottle with her extra toes did the trick," Kelsey told Love Meow. KelseyOnce Fallon opened her eyes, she was ready for adventure. After each feeding, she toddled around with wide, curious eyes, eager to explore. Her extra toes seemed to help her with balance, and she kneaded her blankets enthusiastically with her oversized "mittens."As soon as her legs strengthened, she began hopping off small pieces of furniture, testing her limits, and attempting to climb anything she could get her paws on. KelseyShe zipped around the house like a miniature supervisor, watching her foster mom and the resident animals with fascination. "She thrived and just kept on growing."At only one pound, she sported a round belly, a mighty purr engine, and the confidence of a big cat. She greeted her foster mom with squeaky "roars" the moment she entered the room. KelseyAll that energy needed an outlet, and it soon became clear that Fallon would benefit from a friend. As a singleton, she still had to learn proper feline etiquette and how to play appropriately with other cats. "I always kept the idea of finding her a friend in the back of my mind."Tucker, a resident cat who typically wasn't fond of kittens, gave Fallon a warm welcome. "He sniffed her, then rubbed his head on hers." Fallon and TuckerKelseyStill, Fallon craved nonstop play and attention. She would spiral around the room, climb into Kelsey's lap, and roll around like a tiny whirlwind. She longed for a buddy to wrestle and tumble with.Meanwhile, another volunteer, Belinda, was fostering a little singleton of her own who could really use a playmate. KelseyIsla, a tiny tabby, arrived in foster care at two and a half weeks old. Belinda nourished her and watched her flourish. As Isla's playful streak emerged, her need for attention grew right along with her.Belinda's resident cat, Mia, wasn't so sure about the little dynamo, but Isla was determined to find herself a companion. Mia and IslaBelindaWhen Kelsey heard about Isla, she knew the two kittens might be the perfect match. "Their first introduction was interesting. Isla, being a week older, would swat and hiss at Fallon. Twenty-four hours later, they were besties. I think Isla is one of Fallon's favorite things."From that moment on, they explored the house together, leaping off furniture, chasing each other in playful bursts, and teaming up for every bit of mischief they could dream up. Fallon and IslaKelseyThough younger and smaller, Fallon keeps up with Isla's energy and holds her own during every play session. Both arrived as bottle babies and have since grown into boisterous, adventurous young cats."They love to play together and just be near each other. I'm so glad I was able to give Fallon a companion for the rest of her time in foster care." KelseyShare this story with your friends.
