猫咪换食指南:逐渐换食，为避免肠道不适，建议用七天时间逐渐换食。
Guide to switching cat foods: Effect a change gradually! In order to prevent the upset tummies, the suggestion is to change gradually and over a period of seven days.

原因在于：猫咪消化道里的各酶enzyme种已经适应原食物中的成份和类型，如果快速换用不同的食物，消化道里的酶种不能快速适应新食物，因此可能引起猫咪消化不良及肠道不适。
Reason: All kinds of enzymes in a cat's alimentary canal have adapted the ingredients and type of the old food. If a change in food is sudden, alimentary enzymes can not adapt the new food in time, which may cause the cat indigestion and the upset tummies.

以下是我的第二种翻译

Reason: Having adapted the ingredients and type of the old food, all kinds of enzymes in a cat's alimentary canal do not adapt the new one in time if a change in food is sudden, which may cause the cat indigestion and the upset tummies.

以上翻译绝对没有语法及拼写错误，且用词准确、专业、工整。有人有异议的话可以提。
