Sorry guys, lost my laptop charger, therefore my computer was dead for a couple of days.
I was thinking half human and half animal. Like cat ears, tail, increased senses, maybe even a little fur on a normal human skeleton. And if they learned to control it, they could be either animal or human. Such as being able to transform into either a car or a human, or even in-between.
Yes, the main characters will be kidnapped. The scientists will then proceed to infuse their DNA with animal DNA. 

Sorry for disappearing. If you have any further questions, or maybe I accidently missed yours, please let me know.
