Yeah they are. When the dog stops barking at the snake for moving so slowly that it freaks him out. When the snake stops thumping against the container to get at the frog and/or spider. When the spider stops thumping around in his container to get at the snake. When the frog shuts the he*ll up and stops croaking about "where's the dog?" [spoiler]The frog only croaks when the dog isn't around.[/spoiler]
