Slick, I'm sorry to hear Merlin has stud tail - I had to look it up, too. I'm sure you have already researched it, but here's a link anyway: http://www.purrinlot.com/cat-stud-tail.htm

I hope it clears up and I hope that the medicine will keep him calm while he's being groomed. I have not heard of Acevet. Of the medicine Fister has tried, Diazepam works best (2-5 mg., but he is big). I have given him that a few times on NY Eve.

Kisses to your wonderful boy from me and purrs from Fister. Heal up well, Merlin!
