one day, i came over to her house for a visit. just to be helpful, i decided to feed the kitties. each feline gets her own food dish lest they fight over which one eats how much.
as they were eating, i heard:

"slurp-slurp!"

"sllluuurrrppp!"

"slurp-sluuurp-ssslurp!"
EACH INDIVIDUAL CAT was making her own distinctive slurping sound... and i could actually hear the difference!
i was so amused i started giggling. the cats heard me and looked up with a 'you're weird' expression... and then continued eating.
figures.
too bad animals can't appreciate a CI moment!
