Cats will let you know if they want to be petted, brushed, for you turn on the sink so they can drink from it, or of course be fed. They will also make it clear if they are excited or if they feel threatened. They can communicate just fine when they want to. There are animal handlers and zookeepers who have trained cats to perform complex tasks on obstacle courses repeatedly & reliably, just like dogs and other animals. I saw this first hand at a zoo myself (I think it was San Diego but I'm not positive). On top of all this, if you have interacted with a lot of cats, it becomes obvious that there is a ton of diversity in their personalities & behavioral patterns, even between siblings. There is no point in discussing 'smarter or dumber' here, their intelligence is just different-- it's unique to their species, as with pretty much every other animal capable of being trained.
