When we first got him as a kitten we thought he was a "she" and named him "Contessa" but always called him/her "Tessy." Now, HE is "Tesla" but we still call him "Tessy,"...lol....
The short-hair (front) is "Glen"...our rescue cat. He came with the name...lol...
Omfg...I love the mix up story...but even more, I love the name "Glen" for a cat LOLOLOLOL!!!!
LOL...Yea... the poor fellow had been badly abused. We just couldn't add to his trauma by giving him a new name to remember, too..
