Anyone keep or have kept newts outside? howd they go through out cold winters? have any die offs? i imagine our climate would be fairly similar to Japan except their winters much colder so there shoudnt be any problems here really? wanting to do an enclosed outdoor biotype with mine but they are still fairly young so in their terrestrial stage so dont want to lose them lol.

The low temperatures here where it doesn't snow won't be a problem. It's the high temps which might be, from what I've read. If you have them outdoors I'd suggest some shade and air circulation.
