Since when were caracals ever domesticated?
Sure it may seem tempting to have such an exotic pet, but do you really wanna risk it?
Imagine one day, your 'kitty cat' gets into a playful mood and bites you. From a normal cat that would hurt but no permanent damage, but from a SERVAL. You might have lost that hand forever! I mean, look at those teeth!

You can get the Serval de-clawed (which I still look down upon) but you cant get the poor thing de-toothed!
