Hello Misuk,
With the hair (fur) samples, you can clean them in a mixture of chloroform and 
methanol if necessary. It's nasty stuff though and will burn right through 
regular latex gloves very quickly. You can mix roughly equal parts into a 
Teflon container (it will dissolve other plastic-like containers as well) and 
shake, then rinse with DI water. 
With the scat, pick out the rocks, dry and grind it. Scat's pretty easy.
Cheers,
