Lol! The middle is more popular here, too- it's a lot sweeter I think.Mine LOVE celery leaves. I will give them the hearts where the leaves are almost solid on the small stalks. Bo likes the little tiny tops with leaves. I don't usually give them much of the beg stalks because it bothers me with the strings.
Tony got a big piece of tops with leaves just the other day and he had the whole thing crammed in his face - sides of his mouth poofed out with celery and leaves hanging out each side!
I think he likes it.
