SKF- My very first show heifer did this.....at a show, with me on the halter!! She just wanted to play and didn't want to hurt me...after she had her fun, she shook off the loose chips, and we walked to tie outs lol.
Our heifers LOVE the cats. They'll let them ride on their backs, and they think it's okay to give them baths....I'm not sure how the cats feel about that though. They get along like the best of friends...it can be pretty cute (lol)
