While there is no standardized test to measure intelligence in cats, researchers have looked at how cats' ability to adapt, their curiosity levels and their need for mental stimulation correlates with their intelligence.

Studies have also looked into their sociability with humans and other pets, as well as their willingness to interact with their owners.  

Speaking to MailOnline, Samantha Watson, Scientific Officer at the RSPCA, explained that measuring intelligence in cats is complex.

She said: 'Scientifically speaking, there is no universal measure of "intelligence" in animals. Each species has evolved to adapt to a different niche. A mental ability that is useful for one species may not benefit the survival of another. Some evidence indicates that particular cat breeds may have tendencies to be more active or friendly with people.  However, every cat is a unique individual, and there is significant variation within those breeds. Every cat has a unique personality, which is shaped by both their genetics and life history.'

Below is our top 7 most intelligent cat breeds.

1 - Abyssinian

Abyssinian cats are very confident in themselves and possess an air of superiority about them. We see them as intelligent because they love to interact with their owners and seem happiest when they are being mentally stimulated.

2 - Bengal

The Bengal cat, which has distinctive leopard-like markings, is regularly listed as one of the most intelligent cat breeds.

Known for their good memory, the cats can easily learn tricks and are able to work out how to open cupboard doors.

Similar to the Abyssinian cat, it is important that these smart kitties are mentally stimulated as otherwise they can become destructive around the home, according to Bengal Cat Care.

3 - Siamese

Known for its beauty, the Siamese cat is also one of the most intelligent of the breeds.

Just like its close relative, the Burmese cat, it can be trained to walk on a lead and respond to basic commands.

These cats are good problem solvers, so need puzzles to provide mental stimulation or play time with their owner to keep them content. 

They have strong personalities and are deemed intelligent as they are very interactive with their owners. 

Due to their sociable nature, Siamese cats often form a strong attachment to their owner, which means they often suffer from separation anxiety and might be better in pairs, or when someone is at home all the time. 

Siamese cats are also very chatty and create a loud cry, more so than other talkative breeds.

4 - Burmese

Burmese cats are often described as having a dog-like personality with their love of human interaction and high levels of intelligence. They are very sociable cats who are happiest by your side and having all your attention. They interact well with children and dogs which can also be a sign of intelligence.

5 - Cornish Rex

The Cornish Rex is a clever and inquisitive breed who will explore every inch of your house if you let them. They really enjoy playing games and human interaction so be prepared to have a cat that will pester you for attention.

6 - Savannah

Savannah cats are highly active and many maintain a wild side to their temperament. This makes them very intelligent and in need of lots of play sessions and/or walks on the lead in order to keep them mentally stimulated/.

7 - Scottish Fold

With their unique folded ears, these unusual looking cats, are among the smartest breeds.

They crave human interaction and want to be challenged, so puzzles and toys are an essential.

As is common with other intelligent cats they do not like to be left alone, so it's preferred to have another cat or cat-friendly dogs.

Despite their intelligence, they are much less active than other cat breeds so owners need to be aware of the already-rounded cats getting overweight.
