My cat, Poppy, loves grass. I have to find the very tender shoots but it soon became evident that she would do anything for grass. I taught her to sit, shake hands, sit up, high five and ring a bell on command...all for grass.
My cat, Penny, was jealous of the attention and treats Poppy was receiving. She learned the tricks by watching Poppy. Now I have 2 cats who will do tricks on command.
