Wild city animals

Cities often encourage wild cats to stay wild, and many have a "catch, sterilize, and release" program. Many also do censuses of cat colonies and have a network of colony caretakers.

The plague has closed down most of New York City's animal shelters.

New York City has the same number of wild cats as house cats.

Rats

Wild cats kill on average .12 rats/day. The calorie intake is:

Cat mass             = 4.5   kg
Rat mass             =  .265 kg
Cat food requirement = 218   Calories/day
Rat kills/day        =   .12 Rats/day
Calories in a rat    = 800   Calories
Calories from rats   =  96   Calories/day
