Hi, if you spray bitter apple on it, they won't eat it or play with it. After doing this for a few times, they will leave it alone. I had Baxter and Cooper using a litter box, with Second Nature Litter, until we fenced our back yard in (about 2 years for Baxter, 1 year for Cooper). Darcy was a rescue, and she came already trained to potty outside
.
Now that the yard is fenced, Baxter still stubbornly uses his litter box--he will run through the potty door from playing outside to poop in his box--ROFL!
The only thing I don't like about the dog litter is that no matter what they say, it DOES track. Plus it HURTS to step on a piece of it! I line the bottom of my pan with several layers of papertowels, then put it inside a trash bag before filling it with litter, so when its time to clean I just bundle up the bag, throw the paper towels in it (in case any pee seeped through), wash it out with soapy water and start again! (I use a trash bag so I don't have to handle the litter as much, plus I didn't know if the plastic pan would absorb urine odor over time).
Hope this helps!
