Let me put it this way, Jack:
Throw a stick for a dog in a field and what will it likely DO?
Run out and pick it up and bring it back to your feet - whereupon you throw it again. And the dog goes rippin' out again, gets the stick and brings it back, so you throw it out again. And the whole thing starts all over. This can often go on for a half-hour, never-mind that it's 92 degrees or it's pouring rain like the day the Ark set to sea.
Try that with a cat...
He will briefly stop and look up at you - with a face that says, "Uh, look Rookie, I guess you're new here... but either you haven't read the Contract, or are a Terminal Idiot. This is the 21st Century. Do you realize that I could Grieve you six ways from Thursday, for even suggesting this???
I think you need to have a long talk with someone...."
And he would go back to licking his paw.
Now - I ASK YOU! WHO is smarter???
