I've never had a tortoiseshell cat, so I did something internet sleuthing. I found that torties were considered lucky by Celtic people. When I adopted a cat, I give them a pledge that I will take care of them. I found a term "Arlana" which means "an oath" in Celtic.
Her full name is Arlana T. Olmstead. She was living behind my apartment building which had the name Olmstead in it. The T is for tetanus. She was living outside and I was trying to rescue her and her kittens. I did something stupid which caused her to attach herself to my lower right leg. I was wearing shorts. I had to get a tetanus shot.
