Frontline! I applied it to the back of the neck of a pure white cat and his neck is all green now! Should I be concerned?

Oh dear - I've never heard of that. I'd call the vet and ask. Might be a reaction to the stuff. Have you used it on him before?

No I never have. I jsut got him in a couple weeks ago and treated the whole gang yesterday for fleas just in case, I have seen a little itching...

I called the vet and they said it should go away in a few days but if not then I can wash it off with a little soap at 4-5 days.

Just curious, but is it the same shade as your little photo of you with the green face? If so, could it be something in the water you both are using:lol3: :lol3:

Well that's odd.
Elliott is white and I used Frontline on him and it didn't change color.
If it was something to be concerned about I'm sure the Vet would know.
