Gatti's experiment incorporated four stray dogs and their urine. Samples were taken of each and the dogs were individually given an opportunity to smell as they pleased for five minutes.
According to a press release, "The result was surprising: all dogs devoted more time to smell the urine samples of the others rather than their own, and this behavior confirmed the hypothesis that dogs seem to know their own smell exactly, they are less interested in their own, and they are therefore self-aware."

October 10th is Taiiku no hi, or Health-Sports Day, a national holiday. It was designated in 1966 to commemorate the opening day of the Tokyo Olympics held in 1964. According to meteorological data, this day is usually sunny every year, so it's when many people choose to hold athletic events.
From the year 2000, the government changed this holiday to the second Monday of October so that people can have a long weekend.

Happy Monday everyone! #milomeetsworld
Raise your paw if you think Mondays should become a second Sunday.

The urine-sniffing test is Gatti's version of the "mirror test" — the traditional method whereby self-awareness has been tested for in the past.
Gatti explained, "The ability to recognize their own image in the mirror is a skill extremely rare in the animal kingdom .... A wide range of species has been observed to fail the test, including several species of monkeys, giant pandas, sea lions, birds, and dogs."
Thus, the study team claims the failure of dogs taking the so-called "mirror test" over the years hasn't really been a failure of dogs at all, but instead the method itself.

Dog Poppy and meerkat Timon in the bath at their home on July 14, 2011 in Dronfield, England. This meerkat and dog have been inseparable ever since four-year-old Timon was sent packing by his meerkat mob. The friendly animal found comfort in the arms of owner John Bent's dog, Poppy, and the unlikely pair have formed a mob of their own - which includes John, his wife, Sally, and their two children. You wouldn't expect a meerkat to be friends with a dog, explained hospice service manager Sally. They tend to stick very much to their own kind. The couple, from Dronfield in Derbyshire, has a collection of exotic critters, which started with a pair of skunks three years ago. Since then their menagerie has grown to include meerkats, raccoons, coatis and kinkajous. However, it is the relationship between six-year-old Chihuahua-Maltese Terrier cross Poppy and Timon, which is most surprising. The are inseparable, said John, who owns a surface coating company. Timon came into the house and instantly struck up a relationship with Poppy, who is just about as small a dog as you can get. Now they do everything together. They go for walks together and play together until they fall asleep on the sofa together. (Photo by Nick Obank / Barcroft Media / Getty Images)
Shere Khan the tiger, Leo the lion and Baloo the bear play outside at the Noah Ark Rehabilitation Centre in LOCUST GROVE, GA. Known as the BLT, or Bear, Lion and Tiger, these most unusual and unlikely animal friends are having to go on a diet after being spoilt too much. For not only do Baloo the bear, Leo the Lion, and Shere Khan the tiger have an unnatural bond, they also have a remarkable appetite too. Devouring almost 100 pounds worth of meat and vegetables a week between them, the rescued big beasts had developed something of an obesity problem. Staff at Noah's Ark Animal Rehabilitation Centre in the state of LOCUST GROVE, GA, decided to stop indulging their favoured guests and to put them on a diet after they each gained 100lbs.

KATMAI NATIONAL PARK, AK - UNDATED: ***EXCLUSIVE***A female coastal brown bear and one-year old grey wolf relax together after fishing for salmon at the Hallo Bay estuary in the Katmai National Park, Alaska. In the seemingly most unlikely animal partnership ever this wild brown bear and grey wolf look just like they are fishing buddies. Showing a heartwarming moment when the pair - both wild -decided to forget their differences, the bizarre duo took an end-of-day break together just three feet apart. Both had spent hours trying to land a big catch during the first day of the annual salmon run in the remote Alaskan wilderness at Hallo Bay estuary, Katmai National Park. The pair - a 700lb female bear and one-year-old wolf - were both spotted by photographer Chris Dodds, 42, from Franklin Centre, Canada. He said: 'They were just three feet apart and they didn't seem the slightest bit worried about each other. It was very unusual. They looked just like a pair of fishing buddies and stayed together like that for at least two hours.' (Photo by Christopher Dodds / Barcroft Media / Getty Images)
