Largest Cat Breeds

Larger than life, and with personalities to match.

1 - Savannah

The beautifully marked savannah cat
The beautiful Savannah cat

The tallest on record stood just over 1 foot 5 inches from shoulder to toe! Many push 20lb in weight. This is down to the fact that they have been bred from Servals, large cats from Africa. As the generations proceed, the cats become more like normal domestic cats in size.

A Maine Coon cat with a beautiful thick long coat lying down
The Maine Coon cat - most popular of the large breeds in the US

The largest of the non-wild cat hybrids. Regularly measure up to 3 foot 6 inches, and weigh between 18 and 25 pounds.

A Norwegian Forest Cat with a big bushy tail climbing a tree
The Norwegian Forest Cat - great size and amazing fur coat

Similar to the Maine Coon, and weighing up to 23 pounds.

4 - Ragdoll

Fluffy, cuddly, friendly cats, but very muscular too. They weigh up to 20lb.

Not yet formally recognised as a breed: these things take time, and this is a ‘new’ type of domestic cat, the result of many years’ selective breeding. There are long- and short-haired varieties, and they weigh up to 24lb.

A distinctively marked british shorthair
A British shorthair cat - she'll grow big enough to handle rough play with a dog like this!

Not oversized – maximum weight around 18lb – but the most popular above-average-size breed in the UK, and now commonly kept worldwide.

7 - The non-pedigree house cat

Standard black and white house cat - available in all sizes!
Standard black and white house cat - available in all sizes!

Given that all possible cat genes can be found in the ‘alley cat’ gene pool, it shouldn’t be so surprising when a monster emerges! A big, cuddly, furry monster, we hasten to add. Non-pedigree cats truly come in all shapes, sizes and colors.

In 2002, I adopted my first ever cat, a male Bengalese cross, from a neighbour who couldn't cope with it.. Anyways, the cat turned out to be female & was pregnant. She birthed six kittens, but one was massive & super furry, a Main Coon😻that I named Big Bear aka Cossack aka Mrs Spoon. She was a pleasure in every way possible - I kept all the kittens, bar two that passed away after birth. All of the kittens were a different type of cat, it was so weird - one was a Tuxedo*Phoebe, another was all black*Panther, a ginger one & the two that didn't pull through were both fluffy & all gray! I didn't know cats birthed different types of domestic cat all at the same time like that - it was strange to see..but in hindsight I'm glad now. That litter are all passed away now, but I'm still adopting cats! They must be old cats with issues Or illnesses that require attention or nobody wants - like my current adoptee Phoebz😸 Cats Protection put out an SOS Christmas 2019 for her. She'd been their longest stay ever at 6 weeks. She was old 15, grumpy & liked to be aggressive, purrrrfect. I thought if nobody takes her by Christmas Day then I'd have her - it's now nearly Christmas 2023 & she's still with us☺️& going strong ♥️ Merry Christmas Everybody Everywhere 🎅🏾🌲🍄🎅🏾⛄🍄🎅🏾🌟

I'm a senior living in a retirement home with a large calico cat. She gets very little exercise, sleeps a lot. She is wonderful company but I worry about her weight. Can you offer any help?

My perfectly normal moggy Paddy (now sadly departed) in his hay day weighed in at 11.5 kilos...he was pure muscle,was rescued as a kitten from the canal,and had a tail measuring 14inches!....I think he was a giant in the moggie world and his heart was as big as his body...I have now got a Ragdoll as homage to my big moggie Paddy
