I would love more information on the blanket bags. Do you remember the name of the company that sells them? I, too, have a difficult cat. I, too, have tried everything. I have ended up at the ER once getting stitches...although, the cat did get the pill, so it was worth it. I think. That pill cost me just over $500.
You know they sell flavored gelcaps online, chicken, beef, bacon. It helps at least. They also sell these sort of blanket bags you put them in and zip up so they can't scratch you and fly around all over the place.
