They called today. Did not answer. I think it's a spoofed number and not really ASPCA. I donate to ASPCA sometimes and they never call, only send e-mails. This caller may be from the same spam calling center as 323-503-2371, a telemarketing call I got two days ago, someone trying to sell car insurance.
Not a scam, it's the ASPCA. I've helped out before, and like the organization in general.
I wish people wouldn't post comments when they have nothing useful to add, like "didn't answer, probably a scam". Your useless messages on this Website are more of a scam. Try answering your phone and being polite once in a while.
