You may be familiar with Scrat, the “saber-toothed squirrel” from the Ice Age movies, but a real one lives in Niagara Falls, New York. This squirrel has an unusual tusk growing out of its lower jaw! Mary Jo Sutter has been feeding the squirrel since it was young. Watch the video of the squirrel who has no fear of humans or cats. Link
I felt sorry for him at first, until I noticed that no bird dared to squabble with him. He ate as much as he wanted. The other birds had to wait.
Which, you know, whatever, it's cool. As long as the squirrel gets along, and she seems to.
