Do I continue to message when they stop responding?

I had a customer reach out to me to reserve a stay. I responded in about an hour and a half, saying I would be delighted to watch her pup! The stay in question was for two full weeks, next month. I walked her through my questions/requirements for such a long stay (accurate vet information with phone number, etc.) and I have not heard back from her. I have only been with Rover for two weeks now, but I have booked four stays in that time and I have always had extremely prompt and excited conversations with the customers who have reached out to me. Is this normal for a customer to become unresponsive? Is it worth it to send a follow-up message asking if they are still interested or would that come off as hassling? Thanks!
