When unaltered cats of opposite gender can meet up anywhere, particularly during the warmer months that make up kitten season, it’s a yowling supershedder event. The felines produce numerous of litters, with an average of four kittens per litter and a few higher than 10. Female cats can get pregnant at 4 months old, and the kittens birthed by each cat can be fathered by more than one randy male. Females can give birth three or four times a year during an average three years of life for an outdoor cat and about 13 for an indoor cat (who should be fixed anyway—come on!). The kittens will have kittens who will have kittens who will have kittens. Even if you don’t crunch the numbers, it’s a sad fate for animals who are in reality domestic pets whose ancestors had the bad fortune to be kicked outdoors.
