Did you know Rabbits are only animals not capable of flushing out external stuff (chemicals etc.) in their eyes by blinking alone ! They need their paws to do that..
So if you manage to tie their paws, it makes them ideal for testing! – testing chemicals, like that hair spray you bought last weekend.
.. and those chemical R&D centre looks like this:

Also, did you know there are leather factories in China who are extremely skilled to skin rabbits “alive”, and process the leather in front of heaps of half dead skinless Rabbits . These companies do not afford 10second X 10workers X 100Rabbits of additional effort needed to ensure they are dead before they are skinned. Google it if you think you can stomach it.
