A few weeks ago we discovered a gray tree frog inside our home. We think he (she?) had been hibernating in a potted plant I brought inside last fall. There is still snow on the ground here in New England, so we bought a terrarium and have been feeding him crickets to keep the little guy going until we can set him free outside when the weather warms up.
Today I noticed the frog is covered in very fine white spots, almost like a dust. Is he/she sick? Is there anything I can do to help?
Suggestions needed for this newbie!
