The Unspayed Cat To Kitten Calculator

There is an urban legend floating around out there that says one cat can reproduce 420,000 kittens in just seven years!  That is unbelievable and baseless, yet no one seems to question it.  The truth is closer to one cat and its offspring will produce nearly 50,000 cats in ten years. Either way, there is one thing that we all can agree on, no matter how you do the math:  there are too many cats and kittens and too few homes!

The Calculate-This calculations below (loosely) apply math to scientific principles as they relate to cat reproduction. Taken into consideration are factors such as a high percentage of owned cats that are neutered and a small percentage of neutered feral cats. Also factored in are annual mortality rates as well as post-weaning survival rates of kittens.

The calculator shows that ONE unspayed cat and her offspring could result in 2905 kittens at 7 years and 49,000 at 10 years!  The numbers are staggering, but with your help, Purr Partners will make an even larger impact on the cat community in Central North Carolina.  

  • The average mature cat can have 3 litters with a total of 12 kittens per year; 10.2 surviving kittens of which 4.7 are female
  • The average litter size is 4 kittens with 15% loss before reaching weaning age (3.4 kittens per litter)
  • Gender ratio per litter averages of males to females is roughly 46.5% female (of 3.4 kittens = 1.8 males and 1.6 females)
  • 35% spay ratio allowance for offspring (unscientific factor balancing owned and stray cats)
  • 20% annual mortality ratio not factored into this equation:
  • An immature cat’s first litter usually consists of 2 kittens versus 4.
  • Unspayed female cats can begin reproducing at 6 months of age and can produce a litter during the same year of birth.
  • 30% feral mortality

Responsible pet owners spay or neuter their pets or adopt from reputable rescues who spay and neuter all their animals before adopting them out.
