A few things things to add to John's request for controversy...
I find that caresheet pretty accurate in the sense that you certainly aren't going to kill salamanders outright by using it the way some so-called caresheets will.
Some problems I have with it include his statement that "All Aneides require a brief hibernation period from December to February". This is a curious statement and I wonder on what it is based since species like lugubris, vagrans, and flavipunctatus tend to be VERY active in the wild from December-February. In fact, that's my preferred time to try and see them. Having lived in both southern and northern CA as well as Oregon, I can tell you that Aneides are certainly active during that time and readily observable as long as temperatures are not freezing.
And of course, his breeding claims...I think the distinction should be made between captive breeding and the collection of gravid females which lay eggs a few weeks later. 'Nuff said!
