I'll add myself to the "nuts" list! I always say "bless you" to my two cats when they sneeze. My tabby, Saima, has allergies. She almost always has a stuffed-up nose and she sneezes on a regular basis. Sometimes she sneezes several times in a row (I think that's her way of "blowing" her nose). So I say "bless you" each time!

"Pshew!"
"Bless you!"
"Pshew!"
"Bless you!"
"Pshew!"
"Bless you! My goodness! So many sneezes!"

Kitty sneezes sound cute.
