Well you'd have to put a PCF into "hibernation" when simulating a breeding cycle, and I don't really recommend that... especially if she really IS a she, and develops eggs, and you have no male to breed her with come spring! Since your frog is from So. Cal, things might just be diff for frogs there than here... they'd still have to have some sort of cycle though.

Now my Whites Tree Frog guys are young, too young to have been through a hibernation cycle prior to me buying them, and here they are with nuptial pads so who knows there
