I grew up on a farm in South Dakota, I think at one time we had between 30 to 50 cats. We never fed them, parents said they had to fend for themselves. I'd see them catch pigeons, cotton tails, rats, mice and snakes. Then my dad brought home a big bad dog that hated cats. He killed all of them he could, except the bigger tom cats, dog didn't mess with the toms.
Anyways, after the cats were exterminated we had rats, big rats all over the place. Pigeon population exploded too.
Today, we have two cats. They have a kitty door, so they can come and go as they want. They never go anywhere except the backyard. They don't know how to kill anything. They do know how to catch things. So far 3 rats and a flopping lizard tail(I don't where the cat got the tail) that they bring inside. The one cat comes in the house drops the rat in front, like "look what I did." I developed a routine to get rid of the rats, so no big deal.
Anyways, my cat story.
