Are quiet grinders actually quiet enough for nervous pets?

Verified-purchase and subreddit reviewers generally confirm that low-vibration grinders like the Casfuy and LuckyTail are noticeably quieter than a corded rotary tool, which helps with skittish animals. However, professional groomers in r/doggrooming repeatedly warn that 'whisper-quiet' marketing often comes at the cost of torque, so thick-nailed large dogs may need a more powerful Dremel-style unit.
