Mevlüde dropped off the feline at the veterinary clinic for street animals run by the Istanbul Metropolitan Municipality, concerned for the health of a black cat roaming around the university campus where she works.
Visitors to the Turkish city, who admire its centuries-old mosques and Ottoman palaces, are often surprised to see cats and dogs making themselves at home on the streets, and watch them taking the best seats in cafes and restaurants without a care for the world.
Like Mevlüde, many Istanbul residents try to help these four-legged friends in their neighborhood, putting out bowls of food and offering shelter by their doors or windows.
Now Istanbul officials are increasing efforts to ensure the good health of the street animals, and thereby of the residents who come into contact with them.
That care can be seen at the "Vetbüs," where Mevlüde brought the black cat because one of its eyes had been closed for several days.
The bus is a mobile clinic stationed for several days in different neighborhoods around the Turkish metropolis.
"We often get in touch with the municipality when we see animals who are in need of care," Mevlüde said, once reassured over the cat's health whose eyes were now wide-open.
"People generally bring the animals that they take care of... so that they are given anti-parasite" treatment, said Nihan Dinçer, a veterinarian working for the Istanbul Metropolitan Municipality (IBB).
And "because people are in constant contact with them, they are also protected," she added.
The attention given by Istanbul residents to caring for street animals partly "comes from the Islamic tradition, and part of it... comes from the structuring of the public space in the Ottoman Empire," Mine Yıldırım, a doctoral candidate at the New School for Social Research in New York, said.
In Ottoman times, people moved between home, the mosque and the market. The streets were the space for the dogs, the researcher said.
Then in the early 20th century there were extermination policies like in the West, and even in the 1990s city officials would put poison on the streets to kill animals, said Yıldırım, coordinator of the collective "Dört Ayaklı Şehir" (Four-legged City).
But an animal protection law passed in 2004 forced municipalities to take care of street animals.
In Istanbul, as well as the mobile clinic, IBB maintains six health centers.
The aim is to vaccinate, sterilize and take care of around 130,000 dogs and 165,000 cats who live on the streets, according to the municipality.
The animals, fitted with a microchip, are then taken back to where they were found, except those which are adopted by individuals during their stay at the health centers.
Due to the development of these services, the municipality has cared for 73,608 animals in 2018 -- that compares with only 2,470 back in 2004.
There hasn't been a single case of rabies in Istanbul since 2016, according to the municipality which employs 100 veterinarians and veterinary technicians.
While the municipality refused to say how much the services cost, Agriculture and Forests Minister Bekir Pakdemirli said last month that his ministry has provided 31 million Turkish lira (around $6 million) of support to local authorities across Turkey for the care of street animals between 2009 and 2018.
"If people knew how much money was spent on these services, maybe people would be more upset, but these figures are not disclosed," Yıldırım commented.
While animals living on Istanbul's streets are often well fed, in the forests surrounding the city, "animals don't have a place to feed themselves," Umut Demir, also a veterinarian at IBB, said during a patrol in Belgrade Forest on Istanbul's European side.
So around a ton of food is distributed each day by vans dispatched full of dry food, toward which dogs come running after hearing the horn.
According to Tuğçe Demirlek, chief veterinarian at Sultangazi district health center, the fact that the animals are well fed and cared for ensures that they are calm and limits any aggressive behavior.
But the number of dogs has remained fairly stable in the past few years despite sterilization efforts. "We sterilize them systematically, but the animals that we do not catch continue to reproduce," she explained.
Puppies continue to be born every year in Istanbul, like a small golden puppy only 40 days old that was found alone, whimpering, on the side of a road.
Once examined and chipped, the dog is put up for adoption, its picture displayed in the Vetbus.
One recent afternoon, the puppy attracted a lot of attention, but it still has not found a home.
"We will try our luck again tomorrow," Dinçer said.
