i clip all my pets nails....but i only dont do the cats that often because shes always climbing trees and using her nails for lots of things, so not only does she wear them down, but they need to be that extra bit longer for all her fun activities my dogs cant stand it and neither can the rats *sigh* but they need it done...so they have to put up with me being a "a horrible person" lol (in their words of course)
