I agree with Chris that if you are worried about getting a species that is known for being a picky eater, then you need to do more research on hognoses! Of course, Westerns are a lot easier to keep in captivity, but they certainly aren't exempt from anorexia and subsequent head scratching and shoulder shrugging by the owners.
I disagree with Chris on information. I have always wanted to bring the subject of on the forums so here goes... I have found that most books dealing with the captive husbandry of reptiles and amphibians are absolutely horrible. I've not read a single one yet that if you followed their advice, you could keep a healthy animal for its entire lifespan. In some cases, if you follow their advice to the tee, you would very quickly wind up with a dead animal. I have found web sites to be a much more credible piece of information, partly because they are being written directly by those who have experience with the species. OF COURSE, the Internet is king of false information, but there are plenty of credible web sites out there.
