It’s so degrading.
I hate it when I have to wear one.
I can’t lick myself anyway, so I don’t need one.

The plastic ones constitute animal abuse. You can get soft fabric cones online that prevent the animal from getting at the surgery, but that are comfortable for the animal. Available in sizes from small cats to large dogs. Some vets already use them, eventually all will.
You want cruel and unusual punishment, I had a vet who used an old Kentucky Fried Chicken Bucket as a “cone of shame” for my dog after treatment. I don’t remember whether it had previously been used as a bucket for chicken or not. If it had he couldn’t bite at his stitches because he was too busy drooling.
