LAS VEGAS - Does it need any explaining? Yes, the iPotty is real and is on display here at CES 2013. CTA Digital, maker of iPad and Kindle accessories - or appcessories - is showing off a number of new iPad toys at the show, but the high-tech solution to potty training is surely turning heads.

The iPotty training system has a built-in case for an iPad and the company says it is the perfect way to keep your toddler on the bowl.

"When you are potty training you have to keep them busy. This keeps them engaged and gives them rewards for the right kind of behavior," said Lois Eiler of CTA Digital. In fact, there are a number of potty training apps already in the app store, including "It's Potty Time." The idea is that you fire up the apps, put your child on the potty and…wait.

The iPotty costs $39.99 (iPad not included, obviously) and is compatible with the iPad 2 and the current model.

Oh, and don't worry, it does come with iPad protection. It has a touch-screen protector to, yes, guard against messy hands and pee. Perhaps that's the real innovation here and CTA should think about making one for adults.
