Hatter has dark nails and I had to take a flashlight to them to see where the quick is. Also my nail trimmer has a "safety latch" that will only allow a little bit of the nail to be put through to be cut. It IS quite nerve racking! Luckily Hatter only needs his nails trimmed every two months. However, on Monday it's time to cut them again...fun times for all....
If you are nervous, it is probably best that you only take off a little at a time...
