Explanation:
This is a question tag that follows the statement "A cat is the natural enemy of a rat".
Since the statement is positive ("A cat is"), the question tag should be negative ("isn't it?"). This maintains the pattern of agreement in the question tag, where a positive statement is followed by a negative tag.
