All new, our special edition Sisal Mother Lode for those clients whose birds like to snip the smaller golf balls off the main baseball right off the bat! It also comes in plastic and wood. We've fastened those balls to the main ball with sisal in order to make the toy last a bit longer. We had to replace the animal beads with a bigger bead that the sisal will fit through. Other than that, it's the spitting hidden of our regular Mother Lode with a little bit more strength. All hardware is stainless steel with 2.0mm chain and a 3.5mm wide jaw quick link.
