Cat Naming

My cat's name is Fred, but when I call out to him I usually shout "Ferdy, ferdy, ferrrrdy" and he will come running to me. He was a rescue cat so I don't know what his name was before. I named him Fred because he is just a plain ordinary type of cat to look at, but I address him as Freddy, Freddykins or Ferdykins, because to me he is so sweet and special.

I don't think it matters what name you give to your cat, and I don't think you need to teach a cat to learn its name. If you always use a specific type of sound to get its attention, a cat will know you are addressing it.
