Dear Li ming,
I'm writing to you to ask you for help.I'm going to Beijing to have a trip for several days.I hope that you can help me to take care of my pet cat Mimi during my leaving.She is very lovely and tame.You just need to feed her 3 times a day,she drinks milk and water,she likes to eat fish and vegetables.But she doesn't eat spicy food.Thank you for helping me,and I'll be back this weekend.
Yours,
Dave
