The relation between Cat and Man came about at the start of the latter's attempt at transitioning from a hunter-gatherer society to an agricultural society (mainly in Egypt, starting around 4000 BCE, though mummified cat remains from as long ago as 7500 BCE have been found on Cyprus). Cat assisted Man in overcoming an inherent efficiency threshold (by protecting food stores against rodents), directly contributing to Man's future success at civilisation.
In brief (if you'll excuse me a few shortcuts from agriculture to the development of written language, religion, science, rational though, and even the concept of "leisure" time), it is BECAUSE of Cat that Man can be a gamer in the first place.
Dogs eat rats, too, yo.
Sorry I have to reject the notion that dogs are smarter than cats. I happen to own both and although very loyal, dogs are as dumb as dirt, so dumb in fact that dogs EAT FECES even thier own.
Eating feces or not is not a measure of intelligence.
Look, arguing animal intelligence is basically a fool's errand anyway. Because "intelligence" is only vaguely defined at best. The only people who care how smart their various fuzzballs are are those who have WAY TOO MUCH invested in said fuzzballs.

Cats can use the toilet. Dogs can save lives in burning buildings. Tomayto, tomahto.
