This one I spotted on Edge "Stop Finding A Graveyard Of Toys Under The Couch" but I reckon it's perfect for stopping our spikey four legged scaley children and our other four legged scaley children and even our no legged scaley children from getting under furniture and whitegoods and doors in when we let them have floor adventure time .
This is a great idea. Sadly, my beardie lives at the library so I'd need hundreds to block the edges of the shelving units, vending machines and other nooks and crannies. As it is, he can roam free in the story room without me having to watch him every second. Good thing its big and has floor to ceiling windows.
