I've recently found a couple of fleas on my younger DCat. I know they can jump on from other sources and survive 24 hours but I don't know where they're coming from.
I frontline her every 4 weeks and she had a dose on Saturday. I've just found another one!
There's no sign of any on our old girl. No one in the house has been bitten.
In fact, our old girl has a bad leg so both DCats have been housebound for a couple of weeks... so... where are the fleas coming from?? Does frontline definitely work??
