Thanks for everyone's input. I just wondered about them as I only recently became aware of them from reading them on some of the posts. Even though I've shopped in quite a few different PetSmart's over the years within a 100 mile radius (traveling, moving, etc.), I never took much notice of them. I barely paid attention to their groomers as trimming nails, bathing and simple hair trims I do myself.
So, it looks like I'll be sticking to my vet. lol
