Just transferred my ball from a 20 gal to a 40 gal yesterday. The top was coming in today so I improvised and covered the top with a painting and weighed it down with books. It wasn't heavy enough as I just found today he's missing. Currently he's set up in the living room, I was going to move him to my bedroom. I've looked for a couple of hours but feel completely lost. Basically all the doors were open and I have no idea how I can find him. I put flower everywhere I believe he could be hiding in so I can track and put plastic bags along the walls. I've put his heater under a towel and his hide on top of it near his enclosure. He's 2 years old and I haven't lost him before. I don't know where to go from here.
