Story
Meet Bella!Bella is a cat whose spirit is as large as her size! her friendliness shines through every interaction, winning over the hearts of everyone she meets and which instantly made her a favourite among the shelter staff. Her sweet demeanor is complemented by a independent streak, making her a delightful companion who doesn`t require constant attention. Bella`s loyalty is unquestionable, always there to offer her comforting purrs and gentle presence. However, Bella prefers to be the only animal in the household, relishing in the undivided attention and love of her human companions. Bella is not just a cat, she`s a friend, a confidante, and a loyal companion.If you`re interested in meeting this lovely lady or have any questions, give us a call at 705-878-4618, send an email to info@hskl.ca or stop by during our open hours.

Story
"Mayo here, still searching for the best forever home a kitty could ask for. I came to KLAWS in July 2025, with an estimated date of birth of June 1st, 2025. Balls, mice, cat trees, and more are all the amazing toys and activities that are on my daily list of things to do. I love running around through the house, chasing my foster siblings. A furry friend in my forever home would help keep me company when the humans are away." KLAWS suggests that kittens go in pairs, or at least a home with friendly fur friends (dogs or cats), they can bond with when the humans are away. Our pets need their own safe space for the first little while to help them become familiar with their new surroundings (environment, smells, sounds, people, pets, etc) to be successful and comfortable in their forever home. Please send an email to 4klaws@gmail.com if you have any questions or are ready to welcome Mayo into your furever family. Adoption Fee: $250 (includes deworm, deflea, vaccinations, microchip, spay) To help us find Mayo a purrfect family, please care and share 🙏🏻🐾❤️ 🐾If you are able to foster for KLAWS, please email 4klaws@gmail.com to request an application. Help us help those in need🐾 #4klaws #4klawskitties #4klawsfosters #adoptdontshop #spayneuter #rescuesareworthit Until there’s none, rescue one 🙏🏼🐾♥️ All KLAWS kitties are required, by signed contract, to be indoor only and not declawed. All adopters are required to stay in touch for the life of the cat, through regular updates via our confidential KLAWS Family group on Facebook or via email. If we are not getting regular updates, a KLAWS representative may call. The follow-ups are purely to assure us of the animals’ wellbeing

Atticus is a sweet boy who would spend all day on your lap if you’d let him! But he is also happy to do his own thing if you’re busy. Atticus is getting top marks for behavior in his foster home, and is in excellent health.

Story
"Hey KLAWS followers, I am Macker, and I came to KLAWS in May 2023. My estimated birthday was on July 4th, so now I am 2 years old. I love playing and hanging out with all of my foster siblings. Most of the day we run around and chase each other. At bedtime, I will seek out my foster humans for some much needed love and attention. A furry friend in my forever home will help to keep me company when the humans are away."

Story
"Hello my fellow followers, Burger here again. I have an estimated date of birth of April 4, 2016 and have been with KLAWS since March 2018. I have been such a good boy in my foster home but would love to find the purrfect furever home. I love to play with all sorts of toys and love to be the center of attention. My foster has even dressed me up and I don't seem to mind much. (See pics in comments 😽) On October 16th I will be going to the vet to have my dental done so I will be fresh and ready to go. My teeth will be all looked after ready to settle into my forever home." For Burger to be the best boy he can be he will require a home with no other pets and someone who can shower him with the love and attention he deserves. He is looking for someone who will help him with his transition and stick with him as he settles into his new home. Burger will require a consistently calm environment to help him be the bestest boy!! Burger eats a special urinary diet and is currently on chlomicalm, which is an anxiety medication, which should be continued in his forever home. Please send an email to 4klaws@gmail.com if you have any questions or are ready to welcome Burger into your furever family. Adoption Fee: $200 (includes deworm, deflea, vaccinations, microchip, neuter) To help us find Burger a purrfect family, please care and share 🙏🏻🐾❤️ 🐾If you are able to foster for KLAWS, please email 4klaws@gmail.com to request an application.
