When I got my first cat (Wuppie), I didn't want him to be alone and I got his sister as well, who I called Mathilda. She was mostly black but with some ginger stripes deep down as well.
According to some survey done in Great Britain, people perceive black cats as not as friendly, not as playful, not as nice. Well, Mathilda was all of the above. She loved people and if they didn't give her the attention immediately, she would jump up in their arms. Giving them the fright of their lives of course.
As for being playful: she loved to play with anything and everything and out of the four cats I had at that time, she was the only one who ever showed any acrobatic tendencies like tight rope walking.
While I was on holiday to Canada back in 2011 my neighbour looked after my gang and one day she couldn't find Mathilda. Which was unusual and she immediately started looking for her. She was hiding under the dresser, already quite ill. When I got home a week later, she had been in hospital, but only a few days later I had to take the decision to let her go.
According to Simon's Cat, today it's Black Cat Day to promote the darker of the felines.
