According to Fatih Dağlı, co-founder of Cat Museum Istanbul, many cats arrived in the city on trading ships trading in
Phoenician times, where they were used to keep the rodent populations down. Later, as the spice and silk trades grew in the
Roman and
Ottoman eras, more cats arrived in ships. According to Ayşe Sabuncu from Cats of Istanbul, during Ottoman times, the vast majority of Istanbul's houses were made of wood, which gave shelter and enabled the proliferation of the mouse and rat populations. This made cats' presence a necessity in the city. Marcel Heijnen, photographer and author of
City Cats of Istanbul, says that the love of the stray cats led to the creation of a full-time profession - that of the
mancacı ("cat sitter"). Mancacıs ensured that the city's cats were fed, and residents could choose to purchase food from them and feed the cats themselves. == Health ==
