Yep, you can keep him. Al caught a lizard at the lake, we gave him a new home in an old pop bottle and caught a few crickets for it. Poor schizophrenic lizard, he was Billy Bob, Bobby, Butler, Lizard and several others before he was officially named Wheat Thin. We found out Wheat Thin was female northern fence lizard who needed quite a bit of care. She didn't even last 24 hours at home. We were planning on keeping her until we could release her next time we got to the lake. Not sure why she died so quickly, could have been too cold at night, not enough water or crickets. My guess is that she was really tired of having her pop bottle shaken! So, we were off with shovels to bury her in an empty lot. Oops, Al dropped her tiny body on the way to the burial site, we haven't seen her since!
