Neither of my Abys, if they escape, will come to me outside. Juni has been know to be outside for a full two days. That is why she doesn't get the chance ordinarily...she has to escape. Chloe is a bit better, but not much better. I have to leave the door ajar and then wait, for Juni and Chloe. I have actually caught Juni once, and still have the scars to prove it.

I think either trapping her or leaving a door open for awhile might do the trick.

Good luck.
