A pair of unaltered cats where the female can have two or more litters per year, can exponentially produce 420,000 offspring over a seven-year period. The best thing you can do for your cat is spay or neuter them.

An unspayed female cat can go into heat at 4 months of age. If left unspayed, she will end up having 2 to 3 litters per year. About 70% of her kittens will end up in shelters and be euthanized. With the economy and limited financial resources, the cats are not getting adopted.
