I am not an expert on rape/canola but I believe they are one and the same.
I do not believe there is anything intrinsically bad about rape oil otherwise nutritionists et al would not be recommending it all the time.
Of course they may be people/animals that are intolerant/allergic to it, but that applies to ANY substance, peanuts for example are not a food from hell unless you happen to suffer from anaphlyactic shock!
If it was potentially deadly to animals I would expect to see reference to it on the ASPCA poison control centre site, it is conspicuous by its absence.
