How Long Does It Take 2 Cats to Turn Into 80 Million?

How Long Does It Take 2 Cats to Turn Into 80 Million?

Eighty million cats is a lot of cats. However, you would be surprised how quickly two cats can become that 80 million. If you let two cats breed at will — and then allow their offspring to breed at will, these two cats will have 80 million progeny within a decade! This assumes two litters per year and 2.8 surviving kittens per litter. Here are the numbers:

First year: 12

Second year: 66

Third year: 382

Fourth year: 2,201

Fifth year: 12,680

Sixth year: 73,041

Seventh year: 420,715

Eighth year: 2,423,316

Ninth year: 13,968,290

Tenth Year: 80,399,780

Wow! If only my bank account would multiply like that!

Shared everywhere! This is an extremely important issue. Thank you for the article.... All my cats are spayed/neutered (and adopted also!)

I have all my house critters spayed or neutered. I live on a farm and have barn cats... every year a few new ones show up and a few disappear, the number stays fairly constant..... as long as I take the kittens and find them homes. This is what I have done for years, and with great success; all the kittens that i caught I tamed and found homes for. This must stop! I am not doing the cats of the world any favors! Last year i found homes for 50 barn kittens! I was happy about that, until it dawned on me, my 50 saved kittens, took 50 homes from other kittens or cats. Did they die so these barn kittens could live? I am raising funds to spay and neuter my barn cats (I am on a disability income) now, and I hope to have it all done (fingers crossed) before the spring kitten season. Some are pregnant now, unfortuantly but I will endevor to find homes that agree to spaying/neutering. If everyone would do what ever they can... we will lower the euthanasia numbers and save cat lives!

All of my babies have been desexed. I wish everyone would be so responsible as some pet owners just don't get it!!!

Thank you for reminding people to sterilize their pets.
Both cats and dogs can reproduce very quickly, filling the shelters with unwanted animals, lots of which will die or never be adopted.
Always adopt & sterilize.

WOW! Really, WOW! Spaying and neutering seems to be the answer.

So in 20 years you get about 650 trillion, right? Same thing happens in nature, right? But then there's the factor of food supply, predators, and disease. Our barn cats, which we can't catch, seem to maintain a fairly steady population.

Adorable. but rack off and let me sleep, you'll get yours tonight. Thank you for caring and sharing.

Right. I get in that position for 30 minutes and never move again. I would need a Life Alert butto…

Interesting. Thank you for posting.

Watch your cats behavior closely because they are good at hiding things until it's almost too late.
