If you ask people, “What’s the meanest cat breed?” the Siamese will be one of the first breeds mentioned. Despite their striking blue eyes and elegant body, the cute Siamese has a reputation of being jealous, aggressive, and territorial.
One of the most unique domestic cat breeds, the Sphynx is a cat that thrives on attention and is happy to receive it from everyone she meets. Interestingly, the breed wasn’t created intentionally but came into being after a litter of hairless kittens was born in Toronto due to a gene mutation.
Have you ever wanted a cat that will act as a watchdog? Then the Cymric will be the perfect addition to your family. This gorgeous cat makes up for the lack of tail with a big cat attitude.
A rare cat breed that steals the hearts with its unique panther-like appearance, the Bombay cat is next in our list of the most aggressive cat breeds. Unlike panthers, Bombay cats are very affectionate towards family members and tend to have a strong bond with their people.
Bengal cats are quite stunning with their leopard spots and graceful bodies. The wild Asian leopard cat is their ancestor, so it’s not surprising that they still have a wild streak in them. Bengal cats are very intelligent, curious, and full of energy.
Do you want a cat that loves to snuggle with you while you watch TV? Then Savannah is NOT the right cat breed for you. This hybrid cat gets a lot of the traits of its serval (an African wildcat) parent and is very active, adventurous, and independent.
The cute appearance of the Scottish Fold is often deceiving. While these majestic short-haired cats bond closely with their owners, they tend to be a bit more aggressive than other breeds and might bite when petted too enthusiastically.
Serval cats are WILD creatures, not domestic kitties. So why are they on this list? Because despite the fact they’re illegal to own in many places, celebrities and Instagram influencers have made them trendy pet to adopt. As you can imagine, forcing a creature that’s made to roam and hunt freely into a small home can make them a bit grumpy!
Don’t let their adorable name and looks fool you, the Pixie Bob ranks among the meanest cat breeds ever. They’re named such because of their resemblance to bobcats. That resemblance isn’t just in looks, either. They share a few common traits with their wild counterpart, too.
The stunning Egyptian Mau is another breed that bonds strongly with its people but not so much with strangers. Overall, they’re fairly shy around people that they don’t know. However, when backed into a corner, their mean streak comes out with a vengeance.
