But then a local lion is accused of killing a famous dog - and the dog’s owner, an inflammatory radio host, goes on a crusade to have the cat declared a nuisance so it can be hunted. But it looks like the lion might have been framed, and a renegade animal activist wants Teddy and Summer to help prove it.

Then a massive local grizzly bear named Sasquatch breaks into the house, causing chaos. In the aftermath, Kandace McCracken discovers that her exceptionally expensive sapphire necklace has vanished.
