I 　33 into my back right pocket to take the money to pay and noticed that there was no money there. I started to get 34 . I knew my purse was in the car and I was sure I had put the 35 in my back right pocket. I looked at the cashier with wet eyes and a 36 look not knowing what to do.

It's 38 , no one would hand that in!”　But she 39 me to. “You never know…” she said.

　　Not long ago, Richard Denniston found himself suffering the same pain that million of other pet owners have faced.

　　His little Scottish dog had a brain tumour （瘤） and would soon die. Like others who faced the problem before him, Dennison just wanted to end his pet's suffering.

　　However, he took one step further.

　　Denniston, an expert who studies animals that have breasts to nurse their young, collected a tiny skin sample （样本） from the dog and took it to his laboratory at Louisiana State University. There he cultured （培育） it and froze it in liquid nitrogen （氮）.

　　From that idea, Denniston started a new technology. Dennistion's company will save pet's DNA for $500 , plus a monthly storage fee of $10 , until cloning （克隆） becomes a reality.

　　Thanks mostly to the contribution of a California multimillionaire , that day may not be so far off.

　　“It could happen extremely soon if everything went on well ,” says Mark Weshusin , a professor leading a dog cloning team. Most experts put successful dog cloning a year to five years down the road. The cost is bound （肯定的） to be expensive at first, but it would drop to a few thousand dollars.

　　Since Dolly, the sheep which was first cloned in 1997, cattle, goats, mice and monkeys have been cloned in labs. Pets are likely to be next.

　　“I really believe that the technology is going to become available （可用的） for many species in the near future,” Denniston says.
