I have been taking my cat here for nail clipping for about a year now since moving to the area.
I do not need to make an appt for the nail clipping - I just show up and they take me right away.
My cat does not enjoy getting his nails trimmed, but he seems to have taken to the staff here and actually seems to enjoy his visits. Five minutes or less and we are in and out.
I would highly recommend this place. It is so hard to find a groomer that will also work with cats. The staff is very friendly and I love the interior of the shop - a sort of shabby chic.
You do need to pay in cash though, but this minor inconvenience is worth it.
