The 12-year-old white gray cat is the tallest in the world

Smokey on May 5 has been recognized as the world's largest known domestic cat.

According to the Guinness Council , the 12-year-old white gray cat lives in Northamton, England, with a pitch of 67.7 decibels - almost the same as a lawn mower. In a video posted on a cat-specific website, Smokey made a hissing sound like a hunch of an angry pigeon.

Smokey first appeared in the press in February 2011, when her employer, Ruth Adams, participated in a pet voice contest and won.

Brother Ruth Adams said Smokey has been living with his family for 3 years now. At home, she has a loud voice that is louder than a 737 when landing, with an average level of 80-85 decibels, even 92 decibels at extreme levels, and only when she smokey sleeps loudly.

Smokey now has its own website http://www.smokeythepurringcat.com and many fans.

The Guinness Council said that the largest sounds of animals can now reach 188 decibels and these are the common low-frequency rhythms of blue whales and fin whales while they communicate.
