These are two kittens who alternated between our yard and the neighbours'. There is a third kitten, as well as their Mom, but they were likely sleeping somewhere. They were having a good time hanging out on the fence at 1700 hrs on May 2, right when the New York Times blog asked as many people as possible around the world to take a photo.
The kittens have been dropped off at the animal shelter, and their mother has been neutered. Their mother is a wild cat and the shelter didn't think that she could be adopted, but they have great hopes for the kittens. The mother will be released back into the wild as soon as she recovers from the surgery.
