Miss Waffles loves latex squeaky balls...however, she has a very tough time picking up even the "small", 2 inch squeaky balls (like the soccer ball ones sold by petsmart and amazon.com). her tiny mouth can't grasp them properly.
years ago, we had a smaller one that my son got from one of those claw vending machines, lol. it was perfect -- i'd say around 1.5 inches.
if you know of any sources for ultra small latex squeaky balls, it would be much appreciated.
