Future Herder??

Guinness makes me giggle.  I think he may have a future in herding.  You see, he's intensely interested in creatures - big and small.  He seems to believe his place on earth is to chase things.

Here, he's eye-balling the cat.  You can just see him wondering what the cat is doing out in the field.

And here, he's chasing the cat up the field.  He chased after it all the way to the fence where the cat climbed up to safety. 

I've seen him do this with the sheep, cats, and dogs.  

What do you think?  Do we have a future herder?  Of just baby hijinks?
