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???
