I have noticed since we moved Gadget food and water dish from the bedroom to the livingroom he straddles his food dish to drink out of his water dish... not sure why he does this.. It's not like he doesn't have enough room to walk over to his water dish...
In order for him to reach his water he either has to straddle his food dish or go around to the side to reach it. I bet he doesn't want to stand on that other type of flooring to reach his water. I know that sounds weird but... Lily is sometimes very reluctant to go from the hall carpet into the tiled bathroom. I think the fact that it looks and feels different makes her hesitate. I can just imagine that's what's going on with Gadget too.
Lina does the same thing. She stands over Boss' food bowl to drink out of his bowl instead of drinking out of her own . You'd think they would want to be lazy and do it the easy way lol.
