Forgive me as I’ve always been a paying customer and appreciate this opportunity.

What is the minimum amount of time I can expect for Nexgard Combo cat to work to be able to safely bring an abandoned young cat into my home, where another indoor cat resides, and so my home isn’t at risk for fleas and anything else possible?

I read instructions and times. I’m asking only due to urgency and looking for experienced feedback from the providers.

Thank you!
