Middle-of-the-night questions

The phone rings at 1 a.m. and the voice of a person whom I like very much says “there are two huge mice chasing each other around my apartment!”
“I’m so sorry” I tell her, meaning every word.
“What do I do?” she asks, genuinely wanting to know.

But the fact is, I don’t know. I could say “call pest control in the morning and hide all your food in the refrigerator” but that doesn’t address the issue of the mice having a rock’n roll good time right in the middle of her bedroom floor right now.
.
What to do…“Make sure they’re not rats” I want to say, but this seems mean and unhelpful.

Make a cheese trail to the door? Meow quietly and hope they’re mice of the low IQ type? Use a fly swatter? What? Really, nothing comes to mind.
