Our dog Shaddow has seperation anxiaty. when ever we leave for a few hours we find stuff he's decided were treats and chewed on in the bedroom (he always takes treats to the bedroom). He's chewed through tin cans that were in the recycling bin in the cubboard. He answers to all the cats names too.
Our old dog, Lexx used to bring his food to katey when she was sick, took her a while to figure out what he was trying to accomplish
Weirdest thing our snakes have done is one escaped and turned up coiled up to the VINAGAR bottle. My guess is he was hungry (we use vinagar to clean the feeding containers between feedings).
