Yes, it is possible. while she is quivering (in the process of pooping) press the toilet quickley, that way, she will poop in the toilet and not on the ground. But be careful, it is very tough to catch them while they quiver. If yours is a baby, it poops every feew minutes, when it is a toddler, it poops ever 1.5 hours, when it is any older that a toddler, it will poop every 2 or 1.5 hours!

Thanks for the Reply, I've actually seen it just about to do the business a few times but didn't realise the Clean up toliet button was also a potty training button
