Help! Need image of...

I need an image/chart/graph something that shows how one unspayed cat (or dog if you have seen one for a dog) can theorhetically reproduce x amount of cats(/dogs) if none of her litters is fixed either... Anyone seen anything like this?! I am wanting to add it into my PowerPoint speech about the imporance of spaying/neutering. Thanks for any help!!

Oh nevermind, I found a pretty good image with dogs!!
