Albert Schweitzer once said: "There are two means of refuge from the miseries of life: music and cats.” Cats are frequently accused of being selfish, but it’s humans who are often being a little selfish when they get a cat – they hope it will give them pleasure. But do cats really consistently improve mood – was Albert Schweitzer right? Research showed that, in line with previous studies, cats could alleviate negative moods but were unlikely to promote positive moods. People’s positive moods were more associated with their partners. So it’s a cautious thumbs-up for cats – they might not make you burst into song, but they’ll take the edge off a bad day. And this is hardly the only way a cat can add colour inside your life. Watch how these little animals can change us, big humans!
