Lab Rats

<div>Been watching alot of old horror movies lately and noticed something. In many of the movies something bad happens and starts with laboratory animals. Rats, Guinea Pigs, Dogs, Monkeys and other lesser known critters all play a big part in real and movie experiments.</div><div><br /></div><div>So what do the Core Four use as laboratory animals? There has always been some speculation the Vimh were used this way but would they have worked for the Vrusk and the Dralasites? Is there a critter that could be used with all Core Four since they are supposed to eat the same food and use the same medical supplies what would they test them on? Or is there a whole slew of critters that tests are run on?</div><div><br /></div><div>Any comments or examples would be appreciated.</div>
