As we noted last week, animal law is a fast growing field. So too is animal forensics.

Late last year, on the heels of Michael Vick's conviction for bankrolling a dogfighting ring, the American Society for the Prevention of Cruelty to Animals (ASPCA) rolled out its first mobile animal CSI unit.

Since then, it has been traveling the country, helping law enforcement to pursue and prosecute animal cruelty offenders.

The high-tech Mobile Animal Crime Scene Investigation Unit -- let's just call it the ASPCAMACSIU to keep it simple -- operates under a forensic veterinarian, Dr. Melinda Merck.

It contains a surgical suite, a digital microscope and x-ray machine, anesthesia/oxygen machine, soil sampler, GPS unit, crime scene tape and blood spatter photo scales. For more information, click here.
