I've had a paw patroller under a blanket in my bedroom undiscovered for nearly a month now. I threw it there quickly when I bought it and just haven't moved it.
I was putting some presents in a wardrobe yesterday when my son walked in, I quickly shut the wardrobe doors on myself (i was half in half out), my son asked what I was doing and I casually said "this is how I put things in here". He accepted it and moved on, I have a very unsuspicious child, lol.
