I lose mine all the time, i have over 40 large plants in my living room she leaves her cage and goes where ever she wants. then when i try to find her its almost impossible. I have been looking right at her and didn't notice til she lunged at my face for getting to close.
I lost one of my tortoises. They were both in their outdoor pen, when I went to bring them in at dusk (I'm an over-protective parent!) I could only find one. Tried to play detective, but could see where he could have got out. Stood in disbelief, wondering if I should go search the neighbour's garden, when I heard tiny munching noises. He was in the lettuce patch, and was so full of veggies he couldn't even be bothered to try to run away!
I loose mine on a daily since he's decided to take over the entire house because his huge free range isn't enough I caught him last night 30ft away on top of the beardies cage taunting them then the other night couldn't find him anywhere walked right by him at least a dozen time to find him on the refrigerator door handle don't ask me how he got on there because I'm still puzzled I can't think of a way he could've reached it in any direction :0
