From publisher blurb:
Once cherished as members of the family, the household pets of humanity have undergone horrifying transformations in the wake of global catastrophe. No longer simply dogs, cats, and rabbits, these mutated creatures are now apex predators in the post-apocalyptic world, their instincts twisted and enhanced by the ravages of radiation, toxic waste, and relentless survival. In this booklet, we uncover the terrifying evolution of these once-faithful companions, now monstrous threats lurking in the remnants of civilization. The familiar bark of a dog or the soft purr of a cat has been replaced by deadly growls and unpredictable aggression, as pets turned predators carve out their existence in a world that no longer offers comfort or safety. The domesticated creatures of old now serve as a grim reminder of the fragile bond between mankind and nature, as these terrifying mutations roam the wasteland, hunting anything that crosses their path. Prepare yourself to face the horrifying pets that humanity once trusted, now turned into dangers beyond imagination.
