In smaller cages should the middle between the max. and the min. temperatures be choosed.
fern, whitethorn, leaves of rose, raspberry, blackberry
When in winter plants of hardware/ garden stores are used, the ferns are often sprayed with pesticides. Thus the leaves have to be cut completely and just the regrwoed leaves can be used as food. Otherwise the animals can die because of the chemicals.
