The cat we got has been really well behaved since we brought it back to ours. It's an indoor cat and, as far as we know, always has been. We've had it for over a month now, it's shown no sign of trouble but, last night and again today, it's started ripping up TV magazines and paper and we are at a loss as it why it's only doing in the past 24 hours. Just wondering if anybody has any ideas?
