Arthur's little 'issue' started up, again. 30 minutes in the collar and he's back to normal

Now I'm wondering if he's just sometimes doing an 'after poop' over cleansing.

Fortunately he is now so accustomed to wearing the collar that he just carries on as usual, except that he can't really do any routine coat maintenance while he's wearing it.

The cause remains a mystery to me AND the vet but having it resolve in less than an hour, instead of over several days, keeps my anxiety under control.

I am going to buy a couple of cans of Hill's food for cats with digestive issues. Well, I'll buy one to see if he will eat it.
