*snicker* Actually, I found a little iPhone/Droid app called “PetMeCat” which has that sound, a purring sound and a meow sound. The angry/fight sound doesn’t have a great deal of effect on Sooty but Frosty leaps into action. If I follow it up with the purring sound, she comes snuggles with me. Kinda funny actually, thanks to this app Frosty has become a lot more snuggly lol.
I just tried playing the wav on my speakers. Both kittens went nuts and are now searching the house for the offender.
