One way to put it

When they are running round the house hissing and spitting at each other or rolling around with hair flying around.

Yesterday, Saff was in the garden hiding behind a pot pissing these two magpies off (think they have a nest somewhere near by) and we think poor Mischa got nipped by one on the neck because he was causing trouble. They are about the same size as the cats so quite big.

Damn things! And they are moulting as they are getting their summer coats. It never ends
