PITTER PATTER RABBITS FEET. Tessa wanted to buy a rabbit. She had liked the Easter bunny when she was a kid, so she decided to raise some bunnies of her own. She went to the store with the intention of buying one rabbit, but she ended up with two newborn rabbits, a male and a female. She named them Patrick and Susan. Well, rabbits, being what they are, it is fairly impossible to have just two rabbits for an extended period of time. She bought them on April 1, 2003. On June 1, she noticed that Patrick and Susan were the proud parents of two newborn rabbits, again one male and one female. She named these new arrivals Thomas and Ursula. On July 1, Patrick and Susan again gave birth to a male and a female rabbit. She named these Vida and Wanda. On August 1, Patrick and Susan again gave birth to a male and a female. But Tess was really surprised to see that Thomas and Ursula also gave birth to a male and a female. Tessa was running out of names, so she didnt bother giving them any. On September 1, Patrick and Susan gave birth to a male and a female and so did Thomas and Ursula, and so did Vida and Wanda.1 Tessa noticed a pattern to the breeding. A pair of rabbits was born. Two months later they bred a pair of rabbits and continued to breed a pair of rabbits every month after that. Tessa wondered, If this keeps up, how many rabbits am I going to have on April, 2004? 1Acutally, Vida was no long Vida and Thomas was no longer Tomas. Tess was worried about maintaining a diverse genetic pool among her bunnies, so she traded the original Thomas and Vida to other breeders and named their replacements with the same names.
