Just one final note guys on the cat episode, Nelson woke from this evenings sleep after his dinner to the other stray cat and man,you would of laughed at the sight of this blind dog running full noise down the drive way straight into the rear bumper of the neighbours car. I know I shouldn't laugh but to see him bounce back of the car, shakes his head and turn around and come back inside with ,I sure it was, a look of "that scared that cat away" I couldn't help but laugh and love him. It is quite amazing as his sense of smell must be excellent as he will run past my two cats to chase any strays.
