What is the most beautiful cat breed according to maths?


We have all heard the theory behind models with symmetrical faces being the most attractive. And now a similar theory has been applied to felines using the “golden ratio”.

New research from All About Cats has utilised this golden ratio to analyse the facial proportions of 46 of the best-known cat breeds to mathematically deduce the most beautiful cats in the world.

We have broken down the statistics for you and the results are pretty interesting.

The 10 most beautiful cat breeds in the world according to the Golden Rule are:

1 – Norwegian Forest

Ratio result = 1.65, difference from Golden Ratio of 1.62 = 0.03

1 – Russian Blue

Ratio result = 1.65, difference from Golden Ratio of 1.62 = 0.03

1 – Manx

Ratio result = 1.59, difference from Golden Ratio of 1.62 = 0.03

4 – Ragamuffin

Ratio result = 1.67, difference from Golden Ratio of 1.62 = 0.05

4 – Siberian

Ratio result = 1.67, difference from Golden Ratio of 1.62 = 0.05

6 – American Curl

Ratio result = 1.56, difference from Golden Ratio of 1.62 = 0.06

7 – Selkirk Rex

Ratio result = 1.69, difference from Golden Ratio of 1.62 = 0.07

7 – Siamese

Ratio result = 1.55, difference from Golden Ratio of 1.62 = 0.07

9 – Maine Coon

Ratio result = 1.71, difference from Golden Ratio of 1.62 = 0.09

10 – Egyptian Mau

Ratio result = 1.72, difference from Golden Ratio of 1.62 = 0.1

10 – Turkish Angora

Ratio result = 1.72, difference from Golden Ratio of 1.62 = 0.1

The top three less visually appealing cat breeds are:

1 – Himalayan

Ratio result = 58.49, difference from Golden Ratio of 1.62 = 56.87

2 – Peterbald

Ratio result = 19.78, difference from Golden Ratio of 1.62 = 18.16

3 – Persian

Ratio result = 7.49, difference from Golden Ratio of 1.62 = 5.87

The Norwegian Forest, the Russian Blue and the Manx have secured a tie for the top spot, all scoring within 0.03 of the golden ratio of 1.62.

It seems that mathematical beauty does not come cheap with a Russian Blue costing between £700 and £1,200. Meanwhile a Norwegian Forest cat costs between £600 and £1,000 and a Manx £300 to £1,000.

At the other end of the spectrum, the Himalayan is the “ugliest” cat breed followed by the Peterbald and Persian cat. Despite their substantially lower ranking for visual appeal, the monetary value of such breeds hardly wanes.

The price range of a Himalayan cat is between £150 and £2,000, that of the relatively rare Peterbald is between £1,200 and £2,300 and the Persian could fetch between £950 and £2,200.

What exactly is the golden ratio?

 If you are wondering why some of your favourite breeds were ranked so low allow us to explain what the golden ratio involves ‑ unfortunately it does not consider your cat’s personality. 

The golden ratio is a mathematical symmetry algorithm that underlies the human perception of attractiveness. The closer we perceive a face or object to this ratio, the more aesthetically appealing it is to our brains, which have a preference for symmetry.

This study used images of 46 of the best-known cat breeds to measure their facial features. As the study was only concerned with ratios, the difference in size between images did not impact the overall result.

The study took measurements for the following features before running the numbers through this golden ratio calculator to obtain the ratio score for each breed:

Equipped with this ratio score, All About Cats were then able to work out the difference between each breed’s score and the golden ratio of 1.62, ranking each breed on how close their ratio score was to the ideal.

The maths may say otherwise but all cats are beautiful to us!
