As someone who has had both cats and dogs and currently has an otherwise well mannered dog who bites when his claws are touched, yes, that is a necessity with some animals.

> You have somebody else come over to cut your cat‘s claws?

I know a number of people that don't feel comfortable doing that, or have cats where you'd need multiple people, or to wrap them, in order to clip their nails.

I definitely don't clip as short as they do at the vet, but I have a great set of clippers, and learned that what works for our cats is to keep the clippers on my desk and clip one or two nails when they come for a midday sit on my lap.
