You know, there are all sorts of people out there and some are asshats. There is a groomer in my area who is one.
Most groomers I have met are great people and animal lovers. They do the job because of their love for animals - not because they want to "make-a-lotta-money". However, there are some who push animals through as fast as possible, and these are the ones to beware of.
The one I am thinking of will take your cat and make all pretenses to be nice to the animal. When you leave, however, her demeanor changes. She doesn't make enough time to work with the animal, so she will put the cat into a crate and dunk it into a soapy water bath. She then opens the crate and rubs the cat quickly to work in some of the soap, then closes it again and dunks it into a plain water bath to rinse off.
The cat is in and out of the crate throughout the appointment for drying and containment. She does brush the cat out ... but that is about it. The entire process takes around 1 hour.
Do you really want your cat to go through this?
Please, when you are looking for a groomer, do your research! Get some references. Do other people send their cats to that person? How do the cats react when they are brought in for grooming?
Use your common sense to choose and don't assume that just because the person is operating a business, they should be trusted with your beloved pet.
