Bloody hell. I only dewormed on a whim they hardly go out for long and don’t hunt. I was surprised they ate the powder so easily. When I got up at 5am one of them had done a massive poo on the cream rug, they have two trays which I cleaned yesterday. Does the powder make them go urgently? How often should I be doing it? I’m used to the three in one flea treatment from the vets but I thought I’d try Advantage instead.
