I had hope I wouldn't still be in this category, but both Roxy and TJ are 3 years old now and they still have not stopped completely.
I have tried EVERYTHING! Nothing worked for them.
Now, the ONLY thing has worked, is that I have them on a good schedule. They eat in the AM and then poop, and I get to flush it.
They eat in the PM and then poop, and I get to flush it.
...Now each time, we have such a party, Good Boy, Good Girl, Whew Who, Whistling, etc....And after they follow me to flush it, we race to the Kitchen to get a treat.
This works so well, that TJ (smart little fellow) comes to get me to show me that he pooped. TJ will also come and get me when Roxy is in the box pooping. He wants his treat
Unfortunately, there are times that 'someone' also has a mid afternoon poop, and since NO ONE is there to get it, they have a poop snack
