The kitty thread got me thinking about other animals with a fondness for people food.
Two of my earliest memories of animals and food concern horses.
My Mother had a ritual with me of making oatmeal raisin cookies. We would always make a few giant cookies and bring those to feed the horses. Looking back I have no idea whose horses they were - they were just the cookie horses as far as I knew! (She must have known the owners and had permission - she wouldn't have just done something like that on her own.) The horses would run to the fence as soon as we got out of the car. They were quite patient and gently took the cookie with a bob of the head - it seemed like they were saying thank you.
My Father would occasionally bring me to visit his friend at the track. The friend owned a race horse. I had never been up close and personal with a horse without a fence separating us and the size of the animal scared me. The owner taught me how to hold my hand with my fingers flat (so they aren't mistaken for baby carrots) when offering a sugar cube as a treat. The horse loved it. And began sniffing me all over searching for more - which reduced me to giggles.
