LONDON — The London zoo is taking stock of an animal you don’t often find behind bars, launching what it says is the first interactive map of the British capital’s domestic cats.

The zoo said recently that its interface would allow Londoners to upload scientific survey-style photos, descriptions and locations of their cats, creating a capital-wide census of the city’s felines.

The map may not ultimately have much in the way of scientific value, but it could prove popular among cat owners.

Even ahead of its launch, the site was filling up with dozens of felines, along with tongue-in-cheek field notes.

Quality control doesn’t appear to be a strong suit of the site. At least one person uploaded a picture of a “Nyancat,” the name given by Internet pranksters to an animated, space-dwelling cat with the body of a Pop-Tart.

But the other listings appeared legitimate.

Officials with the Zoological Society of London said they were launching the map to mark the arrival of two Sumatran tigers, Jae Jae and Melati, at the zoo.
