"Mum, can we get a cat?" Oh dear. It was time. My promises and delays were about to collide and I had to face the music (something by Cat Stevens or The Cure). My son and daughter are both (gulp) cat people, but who has the time and patience to teach a kitten all the house rules? Not me! Luckily, a furry selection of mature and family-friendly cats are waiting for adoption if you know where to find them.
