"I couldn't eat and had to have a day off work because I was so worried!" Katie told The Dodo. "I started thinking of ways I could ask people to look for him other than Facebook and posters. Then had a brainwave and downloaded Tinder."
Tinder, for those who don't know, is an app that allows users to create photo profiles (typically of themselves) and a brief bio, usually in hopes of finding a romantic "match" with other people living in a certain proximity to them. For an extra fee, the app will push a user's profile to even more people in the area.
That's the option Katie used — only, she made her profile about Peanut, and added a plea for folks to keep an eye out for him.
