The furious three-year-old moggy squared up to the enormous beast as it tried to raid his home for food in Thailand last night.
Astonishing pictures show how the tabby fearlessly defended his territory against the wild jumbo and lived up to his namesake.
The “guard kitty” was not intimidated by the enormous beast – capable of killing humans with one step.
But he hilariously turned on his heels and fled empty-trunked after being faced with the furious feline in Nakhon Nayok.
Residents said the Goliath was a 35-year-old “nuisance” named Pai Salick that is known for trampling on people’s gardens in search of food.
Local park ranger Amnat Norasin said: “The elephant lives in the forest but he often walks around the homes at night to look for food. People know who he is.
“The house owner said his cat is aggressive and doesn’t like other animals entering his territory.”
An estimated 2,000 elephants are living in the wild in Thailand and a similar number in captivity. In the wild, they roam through the deep jungle and in the country’s protected national parks.
However, there is a conflict when they come in contact with humans who also use the area of farming and gathering food.
Elephants are a protected animal in Thailand and killing them carries a maximum prison term of up to three years and a fine of 1,000 baht (£25).
