Cat in a Hat!

Guess what was found in my parents' mailbox? Another surprise postcard! Madness! I wonder who would send me this silliness...



I was warned to prepared myself, but I didn't! Aack!


BAM! Totally got hit by surprise.



Ridiculous! A tabby cat in a cat! You know, this cat looks very much like Suppy!



What do you think?

Even though it wasn't signed, can you guess who it was?
