Yesterday afternoon between the time I got out of the shower and lay down for a moment, and the time I sat up to finish getting dressed (ten minutes?) the cat dish turned into a swarm of ants.
So I hosed everything down with diluted dish-soap (which works really well, actually, since it both kills the ants, destroys the scent markers, and is essentially non-toxic) and vacuumed furiously, and seem to have won the battle for the moment. But I am really really tired of the war.
And of course now my bedroom smells of soapy cat-food. Preferable, if mildly nauseating. Ah well.
