My parents don't have a backyard fence but he ran to the neighbors who have a cinder block fence with drain holes at each bottom brick...he went through one of those and into their backyard. They live on an acre too like my parents and their backyard is huge, all desert with little holes everywhere. They have a shed on a cement pad with holes under it, he could've gone there. I leave water in front of those holes. I look everyday and always see lizards, but not him. I miss him so much, I worry about all the bad things that could happen to him out there and wonder if something already did. Hurts. There's so many owls, Hawks, snakes...and other bigger lizards competing for his food. I just don't know where he could've gone, their backyard is huge but I keep seeing only other lizards. My poor little baby, he was the sweetest thing. Now my daughter is fine but I'm still having a really hard time. Just hope he doesn't suffer!
