Alphabet Cats

Tabby fur never ceases to amaze me.  Just found the letter “S” on Ruby.  Lugosi has the letter “N” in his fur (or “Z”, depending from which angle you look at it). I haven´t found any letters in Spider´s fur yet, but it´s only a matter of time!  Maybe it´s part of a secret code, or something?! 😉
