The size of someone's brain doesn't make that person any more or less intelligent than someone else. The same goes for cats. They do have smaller brains than dogs, but they are not less intelligent. In fact, it is possible that they are even smarter than their canine counterparts.

According to research, cats' brains are very similar to human brains. This explains why cats have more complex personalities than dogs. In addition, it seems that cats have better long-term than short-term memory.
