Hi Helen, how is Tiggy doing now?
When I put the frontline on mine the fur gets wet, its impossible to just put it on the skin. The fur stays wet but a few hours later its dry and the fur goes hard, it usuall stays like that for a day or two. She will get rid of the stiffness once she grooms, I think they don't touch the area for a couple of days till the smell and taste had gone.
