Mayumi Kitakata frets about the health and well-being of Chi, her stoic housemate who enjoys treats, indulges a bit too much in the catnip and at about 14 is getting on in years for a feline.
Kitakata, 57, has had pet cats come and go over the years and to help give Chi as many seasons as possible, she has turned to artificial intelligence (AI).
In March, Kitakata became an early adopter of CatsMe!, an AI-driven smartphone application that purports to tell when a cat is feeling pain. That cuts down on the guesswork of when it is necessary to embark on a stressful trip to the veterinarian.

“He is at an age where more and more diseases are going to appear,” Kitakata said. “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.”
The Japan Pet Food Association estimated there were almost 16 million pet cats and dogs in Japan last year, more than the number of children under 15.
Tech start-up Carelogy and researchers at Nihon University developed CatsMe! by training it on 6,000 pictures of cats. The app has been used by more than 230,000 people since its launch last year.
The developers say that it is more than 95 percent accurate and expect that degree to improve as the AI trains on more feline faces.
Nihon University professor Kazuya Edamura said that vets like him can tell to a certain degree whether an animal is in pain or not, but it is a harder task for owners.
“Our statistics show that more than 70 percent of elderly cats have arthritis or pain, but only 2 percent of them actually go to a hospital,” Edamura said. “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.”
Kitakata and Chi live in a central Tokyo apartment with the perfect feline napping spot near a balcony window that overlooks cherry trees five floors below. She monitors Chi’s toilet activity and uses the app to read its face each day.
Kitakata had cats since her mid-20s, including Soran, a brown-striped tom who died about six years ago from cancer at just eight years old.
“If I had noticed it, maybe we could have done cancer treatment earlier or something and it would have helped, but even the vet didn’t know,” she said, tears welling in her eyes. “I might have been able to save him.”
When a hiker fell from a 55m waterfall in wild New Zealand bush, rescuers were forced to evacuate the badly hurt woman without her dog, which could not be found. After strangers raised thousands of dollars for a search, border collie Molly was flown to safety by a helicopter pilot who was determined to reunite the pet and the owner. A week earlier, an emergency rescue helicopter found the woman with bruises and lacerations after a fall at a rocky spot at the waterfall on the South Island’s West Coast. She was airlifted on March 24, but they were forced to
CONFIDENCE BOOSTER: ’After parkour ... you dare to do a lot of things that you think only young people can do,’ a 67-year-old parkour enthusiast said In a corner of suburban Singapore, Betty Boon vaults a guardrail, crawls underneath a slide, executes forward shoulder rolls and scales a steep slope, finishing the course to applause. “Good job,” the 69-year-old’s coach cheers. This is “geriatric parkour,” where about 20 retirees learned to tackle a series of relatively demanding exercises, building their agility and enjoying a sense of camaraderie. Boon, an upbeat grandmother, said learning parkour has aided her confidence and independence as she ages. “When you’re weak, you will be dependent on someone,” she said after sweating it out with her parkour classmates in suburban Toa Payoh,
Chinese dissident artist Gao Zhen (高兟), famous for making provocative satirical sculptures of former Chinese leader Mao Zedong (毛澤東), was tried on Monday over accusations of “defaming national heroes and martyrs,” his wife and a rights group said. Gao, 69, who was detained in 2024 during a visit from the US, faces a maximum three-year prison sentence, said his wife, Zhao Yaliang (趙雅良), and Shane Yi, a researcher at the Chinese Human Rights Defenders group which operates outside the nation. The closed-door, one-day trial took place at Sanhe City People’s Court in Hebei Province neighboring the capital, Beijing, and ended without a
‘TOXIC CLIMATE’: ‘I don’t really recognize Labour anymore... The idea that you can implement far-right ideas in order to stop the far right is nonsense,’ a protester said Tens of thousands of people on Saturday marched through central London to protest against the far right, weeks ahead of local elections and six months after Britain saw one of its largest far-right demonstrations. Organized by hundreds of civic groups, including trade unions, anti-racism campaigners and Muslim representative bodies, Saturday’s Together Alliance event was billed as the biggest in UK history to counter right-wing extremism. A separate pro-Palestinian march had also converged with the main rally. While organizers claimed 500,000 had turned out in total, the police gave a figure of about 50,000. Protesters carrying placards with slogans such as
