I don't think force feeding works. With a post-surgery pet, I had some luck feeding her one kibble at a time,
not that this supplied much nutrition, but it gets them chewing and swallowing so they get back in that pattern.
They begin thinking about eating, and sometimes that prompts the behavior. Much encouragement to Shadow.
You have to sit very quietly and offer one tidbit at a time, at a very slow cadence. It might take more than one
go-around to get her started. Sit quietly, talk softly, that sort of thing.
