Another tree frog stowaway

[LilyPad]

The fridges are hard because they let their temperatures go up quite a bit before kicking on and cooling back down. The more stable the temperature, the lower the risk. A mini fridge would be better though if it was left alone like you said. Beyond that, again, I am not much help. I know that for reptiles that hibernate, you have to allow them to empty their bowels and slow them down slowly, but I am not sure if it would be the same for a frog. I would contact a breeder directly to find out, but that may not be easy considering there are an abundance of them in the wild here and are rarely bred.

If he is calling, he is definitely a *he.* A female might make a startle noise (one soft chirp) but will not call.

As for feeding, I would make sure there is nothing he wouldn't snap up and get impacted with (like moss, stones, or wood chips) and just let them loose. If you track how many you throw in and disappear, then you'll have a good idea of how much he is eating at night and then wont have to deal with too many extras. Even with only slight temperature drops, my greys appetites drops off fairly significantly in the winter, so you may not need to feed too much. I go from feeding about 2 dozen crickets a week (to 2 grey tree frog males) to about 10 a week.

Otherwise, if your fiance is really unhappy about it, you can drive him up to Wisconsin and I'll take care of him for the winter haha.
