Put out wet moss and some water dishes. Then wait till night time if you add water and moss dishes especially in places where they might hide you will find them by feeding time. I hope you find them safe and sound. My frog I have had for the longest time has excaped now twice. Once in the spring and the cat found him, but luckly didnt eat or scratch him, and once yesterday when we found him by our newly set up 55 gallon fish tank.
