Fenrir, a Therapy cat from Michigan, sets a New Guinness World Record for being the tallest living cat


Fenrir, the world's tallest living domestic cat, has made it to the Guinness World Records. The F2 Savannah Cat, which is a cross between a domestic cat and an African serval, stands at an impressive 18.83 inches (47.83 centimetres), surpassing the typical height range of 14 to 17 inches for his breed. Fenrir's unique breed, known for its distinctive heritage, has made his record-breaking height even more impressive. 


Dr. William Powers, a family physician and HIV specialist from Farmington Hills, Michigan, adopted Fenrir at just 12 weeks old. He's now almost three years old and serves as a therapy cat in Dr. Powers' medical practice, offering comfort and support to patients. Beyond his towering stature, Fenrir's loving personality is what truly sets him apart. His gentle demeanour and affectionate disposition have endeared him to many. 

Dr. Powers frequently takes Fenrir to events for cat shelters, emphasizing that the cat's remarkable nature extends far beyond his height. He also notes that Fenrir's genetic makeup contributes to his exceptional height, as he hails from the F2 generation with serval grandparents. 

Fenrir's Guinness World Record achievement has garnered attention and occasionally sparked discussions about fairness, as he is a Savannah cat. However, it's important to note that Guinness allows any cat recognized by The International Cat Association (TICA) to compete for the record. 

In this context, Fenrir, as an F2 Savannah cat, is eligible to vie for this accolade. Interestingly, the record transitioned from measuring the heaviest cat to the tallest to prevent unhealthy practices like force-feeding to inflate a cat's weight.


Dr. Powers spends much time and effort caring for his six cats. He ensures they play outdoors in a spacious enclosure, gives them one-on-one attention, socializes them from an early age, and provides them with enrichment activities. 

His cats have a carefully crafted diet that includes nutritious ingredients such as ground-up pig bones, raw chicken, slow-cooked meats, krill oil, and multivitamins and supplements.

Fenrir, one of Dr. Powers' cats, has a unique personality that adds a delightful dimension to Dr. Powers' life. Fenrir is known for his playful "zoomies" around the room and his love for rough play. 

He has a friendly disposition and approaches strangers with head rubs and affectionate "bunting."

Fenrir's story has reached a global audience, and it's not just his remarkable achievements that captivate people. It's also the strong connections and relationships that are formed through his owner's dedication to feline companionship and therapy services. 

As the Guinness World Record holder for the tallest living domestic cat, Fenrir is a towering example of the incredible bonds between humans and their feline friends.
