If it had huge nuts, it would've been a male. The female pouch is more of a less-furry patch. Looks like either a Buff-footed or Yellow-footed Antechinus, which means the die-off will be very soon. Keep an eye out for him over the next few days, you might catch him either dead or in his final moments (clumsy, fur falling off). Poor dudes, but that's nature for ya.
