I don't know anything about this, but I just wanted to say that I'm so sorry and I hope little Theo heals quickly and fully.
I bring Lexi on the bed with me only on occasion, and only to watch TV with me. Sometimes, out of nowhere, she will just bolt up and start running and jumping around, and it can be hard to catch her. Once or twice, she may have gone right off the bed. Maybe having carpeting in the room has helped.
Feel better, Theo!!
