Morley DOES have that look in his eyes.

My Golden is one that ignores cats - if they ignore her. If they run, like my older cat does, she chases it. They've been together almost 3 years now, and Jagger just hates dogs, but
she's getting better at ignoring Rita. If the cat is in my lap and the dog walks up, she won't run unless Rita smells or licks her; likewise, Rita usually just looks at her and if she doesn't move, she walks right by. The dog wants to play like she does with our kitten, but then Jagger doesn't want to be bothered by him, either!

It Is that chase instinct - a piece of paper can blow by and my dog chases it.....funny, she has absolutely NO interest in balls
