Shopping list

I need some large hairy spiders, rats, newts eyes and bats' fur to go in my cauldron. Does anyone know which kind of shop specialises in these?!!
Actually the kids are bringing in the spiders and I daren't ask them aboutthe rats, cos they might just bring in real one... However, the spider's web stood the course of time over the week-end, so next I am going to hand some gruesome words in it. I must take my witch's besom in tomorrow and that can fly from the ceiling. I quite enjoy this part of teaching, but other parts are really like a red rag to a bull.
