Well, with a proper circuit you /can/ power the whole thing with a 1.5 V
battery, if only for limited time.
Heck, with a 1.5 V battery and suitable circuitry you can generate a
pulse powerful enough to kill at least small animals like flies (ever
heard of electric flyswatters?); I'm not sure whether a cattle fence is
strong enough to accomplish even that.
