My barn cat's tail cut is blue. Could it be infection or dead skin?

My barn cat has been tending a cut on his tail for a week or so. We've tried to keep it clean but now I've noticed the surrounding area is a dark blue color. I actually thought it was mold at first but it's just raised blue skin. Any idea what could be happening?

I am quite concerned that the dark blue skin may be well on its way to a black color. Black colored skin is generally an indication that the skin has died. It is possible that some of the surrounding areas can die off as well, so I would make sure that the affected area is examined and trimmed away. An oral or injectable antibiotic would probably be very beneficial in this case to prevent further harm. Something else like an e-collar plus a steroid/antihistamine would help address some of the itchiness that Sunny is experiencing. If she continues to aggravate the lesion, the healing process can be slowed considerably or stopped entirely. Hope this helps.
