my chins dont seem to make a lot of noise. yeah they squeak/sound like a metal detector at each other, but they never kack at me, when im checking their teeth or picking them up (which timothy hates because he always squirms a lot) but they have never kacked at me, just sometimes squeaked quietly while im holding them. im just wondering because a lot of you guys talk about kacking chins, and i have never actually heard mine do that.:wacko:
