I have no idea whether this is unusual for a cat or not, but I thought I'd share this with you.
Every morning and every evening, Rosie eats a small salad with her cat-food. The mix I give her has baby spinach and other deep greens, and last night she began a successful try at beet-greens along with her baby spinach. I included a picture of one of the brands of greens that she likes, and she likes a few others as well. When I say "likes" I am way understating the truth. She literally *loves* these salads.
When I start ripping the leaves into nickel sized pieces and putting them in her "salad bowl" she makes loud vocal sounds, runs around me and head-butts me over and over in a ritualistic way, and then chows down on the greens, pausing to head-butt me several times while she eats. After eating her salad she becomes quite energetic and wants to play and romp with me. What a funny little kitty!
