Apparently, Riley the cat has too much character, and his new owners gave him back after less than a week. So, on return from Vienna we had to go and pick him up again. However, Riley is so much trouble, that I begged for another cat to distract him. The rescue woman suggested Blackie, a probably older and definitely much calmer creature of similarly large stature. It's worked pretty well so far, although Blackie, a scraggy stray when he arrived with us, seems to be getting rather sleek and fat. He does have a very different temperament to Riley. He does nothing much all day apart from doing purring while being stroked. He also has been trying to teach Riley to be more of a gentleman. While that may not be working our that well, he does at least occupy some of Riley's time, and the two now seem to be quite good friends. So now both cats are advertised together on the rescue website. Hope they find a home soon!
