We are moving to our new house in about 2-3 weeks. I am concerned about Piper and Poppy. Our current house is a 1 story, but our new is a 2 story and the top story overlooks the loft, leaving a big gap in the bottom of the railing. will the kittens fall down?? It would definitely kill them if they did, but I'm not sure if I can keep them trapped up until they learn full instincts... they are 11 weeks old right now.
