Yesterday our cat calender had a featured cat who is
exactly marked like our Houdini..

Here is the scan of the calendar page... followed by our
Houdini. Houdini is a female, and will be less muscular and robust than Sylvester, but the markings are almost identical!
The white chin and whiskers. Houdini's whiskers have suddenly grown much longer, we've noticed so I have a new photo here of her in a sun pool playing with her flying disc toys.

I ran into a lady at the Vet's who had a Tuxedo cat like Houdini and she claimed hers was the smartest cat she ever had!
Houdini therefore is living up to these comments for us IMO.
She has sailed thru her spay surgery easily... not like Weezie who was psychotic from the procedure and drugs and caused us some worry in fact!
