Artificial intelligence (AI) can now detect whether your cat is in pain by looking at its face, using an app built by vets and developers in Japan.
The AI app was trained using 6,000 pictures of cats, and developers say it is more than 95% accurate.
The head of the Animal Medical Centre at Nihon University worked on the app. He said vets like him can tell to a certain degree whether an animal is in pain or not, but it’s harder for owners.
“More than 70% of elderly cats have arthritis or pain, but only 2% of them actually go to a hospital,” said Professor Edamura.
“So rather than a final diagnosis, we use [the app] as a tool to make owners aware of whether the situation is normal or not.”
More than 230,000 people have used the app since it launched in Japan last year.

Mayumi Kitakata lives in Tokyo with her 14-year-old cat Chi. She uses the app to read his face each day.

“He is at an age where more and more diseases are going to appear,” said Ms Kitakata.

“So being able to consult the vet but still reduce the number of visits to the hospital is very important for him and for me.”
