The cat corner scratcher reminds us where cats like to be rubbed

Corner cat scratcher
The video explains it all except one thing I suppose. You can see how domestic cats love to have that area from the corner of mouth moving away across the cheek rubbed or brushed and also down the side of the mouth and under the chin.
There are three glands in that general area: cheek gland, perioral gland and the submandibular gland. This is a motivator for a cat: in rubbing that area she deposits her scent on the corner scratcher. It must make it smell like her which is pleasing, and it feels good. Also under the chin is a place which is inaccessible for a cat

The cat in the photo is probably male because 25% of orange tabbies are female.
I am always stroking and combing (with a flea comb) this area of my cat’s face and of course he loves it. It is an absolute must area to pet and rub; guaranteed success in pleasing your cat.
I am quite critical on what I call ‘cat products‘ but this is one I could buy and try.
P.S. I am not paid for this. It is a genuine, casual look at a cat product which appeals to me. Has anyone tried it and if she what happened?
