Hi CocoButterBall's parent, and, of course, you too, sweet CocoButterBall,
I'm not an FIV parent. I just use Vaseline because it beads the blood.
I'm thinking alcohol probably stings.
Does CocoButterBall live in a multiple cat household? Is that why you feel the need for an antibacterial thing for home testing?
I'm sorry I don't know much about you or FIV. Just love your cat's name and photo!
Wishing you all the best kind of encouraging hugs,
Deb and Nikki -- and, Giz, forever dancing in my heart...
