When to Call Animal Control
Don't read this if you've just had dinner, it's slightly gross.
Now, that being said, if a python starts sleeping in the same bed as your chihuahua, and other animals have been killed by snakes, it might, perhaps, be time to call animal control. This family apparently did not know that. Although the python was in the dogs bed and their cat had recently died under suspicious circumstances, the family did not call animal control.
