Cannot say I've ever experienced a live and kickin lizard dropped into my bed by my feline freind...but sure have had more than enough early wake up calls by 'ol furry britches. And agree, they just want us to move out off of the nice warm bed to take the entire thing over themselves. THAT GOT OLD! We just shut the bedroom door. Ends the problem. Maybe you could place your dog's bed in an area which could also be closed off...to avoid burrowing lizards bothering them at night too. OR, just put the darn cat out for the night! IF it would be safe of course. NO more kitties around here for me...I miss 'em but they DO tend to get too bossy...at least my abby did. That is a strange breed...most are not so demanding of their people.
