Cat owners who love to take pictures of their furry friends now have a new excuse to pull out their smartphones and take a snapshot: It may actually help the cat.
A animal health technology company, Sylvester.ai, has developed an app called Tably that uses the phone's camera to tell whether a feline is feeling pain.
The app detects distress by looking at ear and head position, eye-narrowing, muzzle tension, and how whiskers change. It had been in beta release and is now available for the general public to try on their furry friends.
A 2019 study published in peer-reviewed journal Scientific Reports found that the so-called 'feline grimace scale,' or FGS, is a valid and reliable tool for acute pain assessment in cats.
"It helps human cat owners know if their cat is in pain or not," said Miche Priest, Sylvester.ai's venture lead. "We were able to train a machine using machine learning and a series of images."
The app, previously called Happy or Not, could help young veterinarians, said Dr Liz Ruelle of the Wild Rose Cat Clinic in Calgary, where developers trained the algorithm.
"I love working with cats, have always grown up with cats," she said. "For other colleagues, new grads, who maybe have not had quite so much experience, it can be very daunting to know - is your patient painful?"
An app that learns patterns from images of cat faces can be helpful but cat owners should also look at their pet's whole body, including the tail, for clues about their well-being, said Alice Potter from British animal charity the RSPCA.
"Cats that are worried or scared will hold that tail really tight and tense to them. And then aside from that, there's also just thinking about their behavior in terms of are they eating, drinking, toileting, sleeping like they usually do?"
The company told Wired it plans to make Tably a part of a vet's post-appointment follow-up processes and are currently working with professionals to make it possible.
"It has kind of become its own entity. We're starting with cats, although I think this idea could work with multiple species and grimace scales,” Priest told Wired.
