Ralltiir tiger

a ferocious, feline creature native to the planet Ralltiir, these tigers were cute and cuddly when they were young. However, they grew wicked claws and developed a killing temperment as they matured. This savage demeanor could appear as soon as a few weeks of age, and they developed no sense of loyalty to creatures other than themselves. This meant that animal handlers who worked with Ralltiir tigers in their menageries had to be continually aware of the tiger's actions. Compounding the tiger's unpredictable behavior was the blood madness which was brought on by fear or attack. This sudden desire to kill everything around it emerged during adolescence, and could only be quenched by the taste of blood. The blood madness was most often directed at the weakest individual the tiger could locate, making the kill that much easier.
