Well, for a young Grey that was stuck in a vent covered in cobwebs, burned in a lamp, and soaked in chloramines... it's a miracle that it's alive . For next time a bath in 80F dechlorinated water (90%) and unflavored Pedialyte (10%) would be more appropriate. Think the important thing now is to get it to eat and hope it heals. Keep observing frog and let us know how it goes the next couple days. Good luck!
