Your best option would be to give the shelter a call during business hours and someone there should be able to give you up to date information.
How old do you have to he to Vounteer?
@Samara Grischow, I'm not sure, but I think that they may have an age requirement of 16. You should definitely call WARL on Monday. I'll keep my fingers crossed that I'm wrong!! It sounds like they'd be lucky to have you helping them!!
