The Big House: World's Only Sanctuary for Severely

The Big House Sanctuary & Rehab in Ottawa, Canada, is believed to be the world's only rescue dedicated entirely to severely overweight cats. Founded by Kristine, it provides specialized care for cats with obesity-related medical and mobility issues that traditional shelters often cannot handle.

Kristine was inspired to start the sanctuary after build a cat named Biggie Smalls. He weighed 43.2 pounds. His mobility was severely limited. "Gosh, it was definitely mind-blowing seeing his size," Kristine told Catster. He could only walk a few steps before needing a rest, and getting to the litter box was difficult. His primary medical issues were arthritis and significant dental disease.

The Serious Health Impact of Feline Obesity

Kristine hopes people see past the internet's "chonky" cat trend to recognize the serious health consequences. Excess weight affects nearly every part of a cat's body. Common challenges include arthritis, diabetes, heart disease, kidney disease, difficulty grooming, and reduced mobility. Routine veterinary procedures also become more complicated and risky.

"I know they are loved," she says, "but maybe not in the best way sometimes. Why not have them longer and get to continue that love and companionship?" While treatment can be expensive, Kristine believes prevention through proper portion control is simpler and kinder.

A Customized Care Plan for Each Cat

Every cat arriving at The Big House receives a customized care plan based on medical needs, mobility, and long-term goals. There is no miracle diet. "PORTION CONTROL, PORTION CONTROL, PORTION CONTROL," Kristine emphasizes. The sanctuary feeds the correct calorie count for each cat while creating movement opportunities suited to their abilities.

Methods include puzzle feeders, wand toys, or scattering kibble. Ramps are added to furniture for safe climbing. For cats needing extra support, rehabilitation therapies like underwater treadmills, laser therapy, and massage help improve strength and mobility while easing pain. All programs are developed with the sanctuary's veterinary team to ensure safe, gradual weight loss.

Remarkable Physical and Emotional Transformations

The physical transformations are significant. The sanctuary recently celebrated cats in its care losing more than 130 pounds collectively in a year and a half. Yet Kristine says the emotional changes are often her favorite part.

"The personality changes as they lose weight," she says. When severely overweight, cats are often subdued and mild. Once they move freely, personalities bloom into divas, acrobats, or even little bullies. Their relationship with food remains a challenge. Kristine notes how clever they are at stealing food, recalling Biggie Smalls quietly managing three plates at once.

The sanctuary currently cares for between eight and fifteen cats at a time from a home-based setup. Its mission extends beyond its walls. The team works with shelters, rescues, build homes, and pet owners, providing advice and support to help overweight cats before they reach a crisis. By sharing journeys online, they educate owners about feline obesity and encourage small lifestyle changes.

Kristine dreams of one day opening a dedicated facility to help more cats. For her, success is not measured in pounds. "The most rewarding part is seeing these cats become cats again," she says. Getting second chances and doing basic cat things is magical for them and for the caregivers.
