Gerkat

From Newerth: Savage Wiki

Gerkats are very fast moving feline carnivores that prey on large and small creatures. Out of all of the npcs , Gerkats are most likely the most annoying npcs to face in the beginning of the game, especially for beasts, because of their lack of blocks. They can kill a nomad or scavanger in about 4 shots, and because they are extremely aggressive and because the whole pack of 3 or more will attack you at the same time, you will most likely be killed if you attack them alone. The only part about them that makes them easy to kill is the fact that even though they will attack you orignally at fast speeds, there is a delay time in between their attacks which allows you to attack four times before they attack again, which is enough to kill them.
