It's incredible that female cats and dogs can be pregnant at least twice a year. Every litter can range from 1-10 (or more) puppies/kittens . By the time the little kittens/puppies become 5-6 months old, they can be impregnated too. Now I was never good at arithmetic since I was young, but I can still kind of guesstimate that this equation can quickly multiply.

Here's how it looks, for example:
1st generation
2 (litters/year) X 4 (kittens/litter) = 8 kittens

2nd generation
Say 4 of those kittens were females and can give birth...
in addition to the 1st generation Mama cat...
(4 + 1) X 2 (litters/year) X 4 (kittens/litter) = 40

3rd generation
Again, say half of the kittens were females...
(5 + 20) X 2 (litters/year) X 4 (kittens/litter) = 200

So what can we do to prevent the over-population of kitties and doggies? Do the responsible thing and spay/neuter your cat/dog when appropriate (often when they are 5months old, preferably before they have their first heat). They are 2 ways to go about this: laser or the conventional way to spay/neuter your kitty/doggy. And yes, it may seem cruel to spay/neuter your best friend, but look on the bright side :) There are advantages to spaying/neutering your pet, such as:

• No more heat, so no more bloody spots on your Persian rugs. 
• No more unwanted litters of kittens/puppies.
• Decrease...

Do we even need to say more? Look at how adorable these little kittens are!! They spend 15-18 hours sleeping, 2-3 hours playing and stepping on one another, 1 hour eating and drinking, and about an hour here-and-here licking and cleaning themselves. Oh, and maybe some time here-and-there to pose for pictures :).
