Grumpy Cat ascii is a form of mainly internet art (if you can call it that) which you create by only using the keyboard of a computer. A lot of people like to sign off their comments or emails with a miniature ascii artwork, usually a cat’s ears if they are cat lovers.
“ascii” stands for “American Standard Code for Information Interchange”. It is a character encoding system. Below are some ascii cat images starting with Grumpy cat, which I have judged to be in the public domain.
This last example of ascii cat art was generated online from the photo left.
