I was watching this show on tv where they were checking raccoons for diseases. They'd catch them in a live trap, then drug them, and take a blood sample. Then they left the drugged raccoon curled up near a log. Claiming it was perfectly harmless.
Yeah. Until a grizzly bear waddles by and says "All right! Free raccoon!"
But, you win some you lose some... or something...
Watch out for live traps.
