I've been looking through some spells that require certain animal parts that are sort of unusual, and I was wondering for anyone who uses those kind of ingredients where you find them. Huge range from things like feathers and teeth to 'eye of night owl', snake skin, bones, etc. I know there are some who go to the zoo and try and get discarded castoffs like teeth and fur, but that's kind of limited. There are also biological supply companies that cater to dissection classes and such, but that also has limits (not to mention... dead and preserved with lots of funky chemicals). So for anyone who uses those kind of ingredients in magic, I'd be interested to know where or how you find them.
