8. Playful behavior is a sure sign of a happy cat
Older cats may play less but they still have a sense of fun and will interact in a playful way with owners who make them happy, as well as with other household pets they like and trust. Cats will show you they are happy and want to play in a number of ways, perhaps by lying on their side and twitching their tail. Cats will happily chase lights from laser pens or balls of paper and string, there is no need to buy expensive toys – it’s the interaction that makes them happy.
