Hi Jaclyn,
I have never kept or rescued a gargoyle, but I found this care sheet.

I hope this helps you with basic care. I would also suggest that you post in the gecko section where you might get better responses. As for rescues, do a google search for reptile rescues in the Seattle area.

I would also suggest that you check pet finders. Do a search as if you were looking for a pet, and if there are rescues near you, they will pop up.I think that site is listed through the SPCA, but not sure.

You can also check the rescue listings here and see if there is a reptile rescue near you.

I hope this helps. Hopefully someone who knows crested gecko and gargoyle care will come along soon. According to that page, their care is similar.

Good luck!
