Thank you all for your responses. None of you know me so I guess I can't be too annoyed that some of you apparently think I'm an idiot. I made no mention that I intended to forego outdoor forays with my pup, so not sure why anyone would make negative assumptions. I happen to live in an area of the country that gets heavy snow. Just a few days ago it snowed so heavily that not even I could step outside my front door until the snow removal company we contract came and cleared the snow (near the end of the day). A puppy would have been swallowed by snow. So on such days as that, and perhaps on those hopefully rare occasions when I'm late getting home or sick in bed with the flu, I want my puppy to be able to potty. It's miserable to have to hold it and I don't want my puppy to ever be uncomfortable. I also own an apartment in a high-rise near New York that I stay in from time to time and I'm on a high floor. No need to explain why an indoor potty system might be useful, even necessary on occasion in a high-rise. So please know that I plan to take Puppy on long walks at least twice a day, crate train her, groom her regularly, feed her healthy food, get regular vet checkups and be an all-around responsible pet owner. And on those occasions when Puppy must wee wee in her indoor potty box, I will clean and disinfect it right away. So SisMorphine, does that make me any less gross? For anyone who might be interested, I've spent a ridiculous amount of time searching the Web for any and everything I can read about indoor potty systems. I think I'm going to end up getting a Pup-head. It's half as expensive as the PetaPotty and people who have one seem to really like it. People seem to really like the PetaPotty too, but for the price I think I'm gonna try the Pup-head. Thanks again for your input.
