Nah,

They were great about it. They are animal lovers. I set the trap up today at lunch. Just took a quick jaunt to check it and it's empty still. I'll come in early and check it. It's pretty unobtrusive so no one will bother it or the cat, should she decide to go in it. The shop guys have told me she was wandering around looking for her babies this morning.

Babies are fine. Saw them at lunch. Made a deal with the shelter director. If I trap her, they'll assess her, de-flea her, do her shots and a complete check up. If she's feral, or even semi-feral, I agreed to take her to my house with a cage so I can work with her in the spare bedroom, rather than taking the chance of them just putting her down. I'm keeping my fingers crossed.
