To whomever it was on here who suggested cornflour to stop the bleeding after accidentally nicking the quick when clipping claws - it's just worked a treat.
My boys have just been bathed and clipped and Smooth was being stroppy and I nicked him. From somewhere in my grey matter I recalled this tip and deposited a bleeding pig on my DD (she was not pleased but the pig was eating cucumber and quite happy) then rummaged to get the cornflour. It really worked.
So a big thank you to whichever of you it was and to everyone who gives such great advice on here all the time.
