Brain teasers are a great way to give your mind a workout while keeping it occupied.
While some determine intelligence levels, others can tell users about different personality traits. Of course there are plenty that exist just for fun.
That's what this latest puzzle serves to do and those who are particularly fond of felines will really enjoy it.
Not only do they keep you entertained, but studies have shown that brainteasers can help boost cognitive skills such as memory. Some medical experts have suggested that regularly doing puzzles could help ward off conditions like dementia.
