As far as your cat’s concerned, play has always been the perfect way to practise her hunting skills. This natural behaviour doesn’t change just because she’s got a little bit older. In fact, your cat may continue to chase toys or play hide-and-seek until her legs simply won’t let her!
All the same, you’ll probably find that your older cat doesn’t have quite as much energy as she did before. In fact, this reduction in activity might be the only visible sign that she’s getting older at all.
