If you have a shower stall with a door that is a great place to groom a cat because there is no place for them to run.

Krista loves it for her cheeks but I have seen her slink through it a few times. I just got it yesterday so that kind of adoption rate for something new is pretty phenomenal. I'm sure she'll get the hang of it over time.
I have a similar groomer; I showed Melody how to use it by using it myself...kind of glad it didn't take too many demonstrations!
As for grooming in a shower stall, I'm hesitant to get into one with Master Shredder. I will take my time and just suck it up for now with more sweeping and vacuuming I just need to establish a higher level of comfort (and trust) to get to where I want him to be.If you have a shower stall with a door that is a great place to groom a cat because there is no place for them to run.
