Found sluggish baby at work.

Afternoon all. I found this pretty young thing on the drain grate in the wash bay of the tractor trailer dealership i work at. He/She was extremely cold and sluggish (but not so sluggish to keep from musking!) I decided on bringing home. I washed out an old critter keeper and used paper pellets ( we use them for the python, the rabbit, cat litter its great!) Seems far less sluggish now. My question is should i attempt a release now or in the spring? I may not be able to let go in the spring haha. My feeling is that it its too late in the year for a reasonable expectation of survival. Should have been underground by now. I think those couple of freaky 70 degree days brought her out. No idea where she came from. The shop is a ways from any water and i can't see much food around the concrete and blacktop where i work. Opinions?
