Extra iFetch Balls

One order of iFetch balls will include 5 balls.- iFetch balls are manufactured for optimal operation with the iFetch ball launcher.- iFetch balls are 1 1/2″ diameter and are not full sized tennis balls.- Some similar pet balls (40mm or 1 ½” diameter) will work.- Some balls, even if the right size, will not work or may be hazardous when launched.- Some dogs slobber more than others. If your dog is a heavy slobberer the iFetch may require wiping off balls from time to time, making it difficult for the dog to play continuously by itself.
