My cat had mild abdominal surgery recently for a rescinded testicle. When he came back I spoilt him terribly gave him a cuddle and then left him to recover. He had fur shaved on his two front paws (IVs?) and his abdomen - but I can't say I noticed his neck! Checked him earlier and there is a furless patch on his neck, about 20p sized, with what looks like a big scab. Is this from the operation, as in will they have done something to his neck? Or is it something else? It's been about two/three weeks since the op if that helps.
