Years ago, back when blind Hiker was adopted, I searched for toys that would make some noise so she could find them. One of the best and least expensive was a yellow plastic ball from the dollar store. Since it has nubby things all over it, it made a slight noise rolling on the icy snow in the yard and the floors in the house.
Hiker wasn't (and still isn't) overly interested in playing with toys. Callie however, discovered the yellow ball and it became one of her favourites and she would even pose for pictures with it.
Since it was so popular, we had a few extras on hand. Now we are playing with the last one. The dollar store doesn't stock these any more and every time we see a dollar store we stop in to no avail. We've checked in both Canada and the United States.
The last one is not in good condition.
Callie still plays fetch with it but we don't know for how much longer.
