I have tried looking around the DPAW site but like any government funded program's website it isn't the easiest to navigate. Also I couldn't find the information I was looking for. At first I was under the impression that as long as it is healthy for a reptile you can use pretty much any suitable substrate in an enclosure in WA. I spoke to a breeder a couple of days ago and she told me that in WA keepers and breeders are only allowed to use newspaper and pelleted newspaper as substrates in reptile enclosures. I thought this was odd seeing as I have seen people using anything from sand to alpine chips and the same in a pet store I visited. Since I have looked for any documentation by DPAW regarding this but nothing so far. Is it something they tell you and simply do not enforce unless problems arise or is it just something I misinterpreted or that was explained incorrectly to me? Anyone in WA with experience or who have had people from DPAW come to inspect enclosures (eg. when you got your cat5?) and what kind of feedback did they give you regarding this? Just wanting this cleared up for me before I look at designing an enclosure, thanks .
