Hurricanes, earthquakes, volcanoes, wars, tsunamis, you name it.
If you're a Christian, you've got a big problem on your hands. After you're swept away to walk the streets of gold with Jesus, red hot lava is going to pour from Mt. St. Helens and right over your dog, leaving his burned body encased for millennia until discovered by godless alien archeologists. And what do you suppose they'll do to his charred yet supple and hermetically sealed haunches? They are godless after all. (What would you do? That long space voyage sure can be lonely.)
JesusPets has the solution. For a modest fee you can live for eternity relatively guilt-free knowing a JesusPets animal lover took care of your dog for the rest of his or her natural life.
