But what if there is only one flea not a lot?

Please provide me with more context! I need to know what you're asking about in order to understand your question. For example:

* What are you talking about? Is it a situation with fleas, a scientific experiment, or something else entirely?

* What's the significance of there being only one flea? Does it change the outcome of something?

Once you give me more information, I can give you a helpful answer. 😊
