Rank the animals most likely to survive a zombie apocalypse.

Survival in a collapse scenario often comes down to adaptability, stealth, and nutritional independence. If we look at these traits, here is a ranking of animals likely to fare well:

1. Rats: They are the ultimate survivors. They are highly intelligent, can eat almost anything, thrive in urban environments, and are small enough to hide in places zombies—and even humans—cannot reach. Their reproductive rate ensures their population recovers quickly.
2. Crows/Ravens: Highly intelligent problem-solvers, they can learn to avoid danger and find food sources from the air. Their ability to scavenge and communicate with each other makes them exceptionally well-suited for a world where traditional food chains are disrupted.
3. Feral Cats: These are apex predators that remain small and elusive. Unlike domestic pets, feral cats have retained their hunting instincts and are expert at staying out of sight. They thrive on the rodents that would likely see a population boom in an apocalypse.
4. Wild Boar: They are hardy, aggressive, and possess a varied diet. They are strong enough to defend themselves against most threats and are adaptable to almost any climate or terrain, making them one of the most resilient large mammals.
5. Cockroaches: While not an animal in the vertebrate sense, they are worth mentioning for their sheer durability. They are nocturnal, eat waste, and are nearly impossible to eradicate. They would likely outlast everything else on this list.

Why others might struggle:

• Domesticated animals: Dogs, horses, and cattle rely heavily on human infrastructure for food, medical care, and protection. Without humans to maintain fences or provide feed, their survival rates would drop significantly.
• Specialized Predators: Animals like lions or polar bears rely on specific territories and prey populations. If their ecosystem shifts rapidly, they struggle to adapt as quickly as the generalist scavengers listed above.

What do you think is the biggest challenge animals would face in such a scenario? I'm happy to look into the specifics if you have a certain species or environment in mind.
