land turtles

Question
are wood chips bad for my pet turtles cage

Answer
This depends on what kind of land turtle it is, but for most- yes.

A decent substrate for most tortoises and box turtles is a mix of sand, loam or leaf mulch, and shredded bark (cyprus, coconut, or pre-soaked Bed-a-Beast). Change the mix depending on how much humidity you need- more humidity, more mulch and bark.

More and more, however, the recommendation for high-humidity land turtles is to use long sphagnum moss soaked in warm water, layered about 3" thick.
