Why does NYC have a huge rat problem?

Question

I heard stories of the rats attacking people, swarming them and being so huge. They look scary.

 I'd be traumatized if I was swarmed by huge rats. They also attack pets. 

Update:

I've also heard about the huge roaches. 

Answer 1

Favourite answer

It has a big rat problem because stupid people litter food everywhere. The more food that gets littered, the more rats will be attracted to the area.

Having pet cats would help with the rodent problem. You say that rats attack pets... I'd love to see a rodent mess with a kitty! They won't live to tell the tale

Answer 2

Those stories are probably exaggerated or even fabricated altogether.

Answer 3

It doesnt. Its mostly urban legend. The rat population is currently estimated at around 2 million, which is a lot, but not like theres swarms of rats patrolling the city and attacking people. And, for the most part, theyre normal sized rats

Answer 4

they have rats as big as dogs

Answer 5

More people need pet snakes.
