I am not onboard with a groomer than upsets their fur-clients.

Why do you feel they need to be taken to a groomer? For a start, (I am not sure of this,) but it is my understanding that unless they are flea ridden and really dirty, bathing them is not a good idea.

Brushing them yourself should be enough, and will provide both you and the cats with soothing time together. Brushing helps to release the oils in their fur and loosens old hair. There are a ton of great grooming things on the market.

The very idea of anyone "manhandling" my cats is unthinkable. Poor kitties.
