No matter how cute they are, do not invite felines. After all, the term “catty” derives from somewhere.
You do not have tacky plastic decorations on your lawn. The only exception is if it is named “Marcus the Carcass.”
You do have a coloring area but do not use anything labeled “permanent marker” unless you want a permanent reminder of your party.
You do not make the mistake of calling a [big mean] Tomcat a [woosy little] Kitty.
You do not attempt a group shot. Ever.
