Two kittens found at a family's doorstep as newborns stayed together and grew into the sweetest cats. Hermione and GriffonChatonsOrphelinsMontrealTwo tiny kittens with their eyes still closed were found outside and in desperate need of help.Shortly after they were born, their feral mother carried them to a family's front door, left them there, and never returned. One of the kittens was cold to the touch and barely responsive. Realizing they needed rescue, the family brought them inside.They carefully warmed the kittens, and before long, the weaker sibling began to move again. They were found as newborns outside a family's front doorChatonsOrphelinsMontrealBarely a day old, the kittens had no chance of surviving outdoors on their own. With little experience caring for newborns, the family reached out for help. That night, the two were transported to Chatons Orphelins Montreal, an all-volunteer rescue, where they were named Hermione and Griffon.The kittens were incredibly small for their age, weighing just 64 and 72 grams, respectively. Their tiny size suggested they had likely been born prematurely. ChatonsOrphelinsMontreal"At this age and weight, and without a mother, the margin for error is slim, and the chances of survival are low. They needed specialized care," Chatons Orphelins Montreal shared with LoveMeow.An experienced foster volunteer immediately took them in, providing round-the-clock bottle feedings and constant monitoring. Thanks to her dedication, the fragile kittens started to gain weight and strength. ChatonsOrphelinsMontreal"They were weighed daily to ensure they were growing steadily. On several occasions, when they struggled to feed, tube-feeding was necessary to make sure they received the nutrition they needed."Griffon had a more difficult start and often lagged behind his sister. But his foster carer never gave up on him. In time, both kittens surpassed the 200-gram mark and continued to grow stronger each day. ChatonsOrphelinsMontreal"They are little warriors who have grown into lively, spirited kittens."From the beginning, Hermione and Griffon shared an inseparable bond. Wherever one went, the other was never far behind. Once their legs were strong enough to carry them beyond their nest, they eagerly explored their surroundings, turning every corner into an adventure. They share an inseparable bondChatonsOrphelinsMontrealTheir personalities complement each other perfectly. Hermione, the dilute calico, is the bolder of the two. Fearless and confident, she isn't intimidated by anything, not even a large dog. She is also quite vocal and never hesitates to make her opinions known.She loves wrestling with her brother, batting toys around, and climbing anything she can reach. If there's mischief to be found, chances are Hermione will discover it first. ChatonsOrphelinsMontrealGriffon, the gray kitten, is the calmer sibling. Though more laid-back, he has developed a playful and mischievous side and never misses an opportunity to roughhouse with his sister. "He loves being picked up and snuggling close to us. The moment we touch him, he starts purring."Together, the brother and sister spend their days playing, exploring, and enjoying the company of the resident cats. ChatonsOrphelinsMontrealThe kittens who once fit in the palm of a hand are now thriving in foster care, surrounded by people who have poured love, time, and care into their journey. Today, they are healthy, happy, and full of life.Though much has changed since they were found on that doorstep, one thing remains the same: the unbreakable bond they share.
