Good job, Otis!!
I have noticed that Toto can hold it for long periods of time. If we have to leave her alone, even though she is in her X-pen with all the comforts, when we return ... the pad is dry ... no food missing ... no evidence of anything except a long nap! As soon as I open her gate and she has kissed us she immediately runs in there and has a nice long pee, drinks and grabs a snack and then runs back to us and finishes her "hello"!!
OK, I'm off to order those PJ's!!
