Wow thanks so much for the infos!! I have 3 cats and 2 big dogs so will definitely try these.
Anybody have a good recipe to repel the cats from digging in my garden / flower beds? Not only they use them as litter box but they come out if it pretty dirty. The garden hose works when I am around but I cannot follow them all the time LOL
I did tried the coffee grinds and mothballs without success. May be I am burrying my balls too deep I don't want this on their paws I guess it would be poisonous.
