Answer the question. – Are my cats running now? – No,

The question asks for a response to "Are my cats running now?". The provided answer fragment is "No,". To complete the sentence logically, one would typically add a verb or a phrase indicating what the cats are doing instead, or simply state they are not running. Given the context of a simple question-answer format, a direct and common response would be to negate the action. Therefore, a suitable completion would be to state they are not running, or to provide an alternative activity. However, without further context or options, the most direct completion of the provided fragment is to simply acknowledge the negation. Answer: No, they are not.

No, they are not.
