You're always helpful! That's a really good idea honestly. I think I'll do that so they learn where everything is and how to avoid the edge before I raise it up again. You're so smart.You could maybe lower the platform to start with until they realise not to go over the edge of the platform... I don´t know if they would learn... Sorry if I´m not much help, I´m just throwing out ideas
The platform has a rim about 1" high, though it's hard to tell in the photo. Hopefully they'll learn to recognise that as the edge.
