I've always loved dogs and think they are much smarter than cats..never owned a cat although my neighbour has a lovely Persian which I admire from afar..but would never touch...

Give me a dog any day. We have had cats in the past but they are so up themselves and only come to you when it is meal time.

We have  two dogs, a his and hers! We love them as part of the family. I can't stand cats and have no patience with them. I hate it when they brush past my legs.

In my opinion dogs are cleverer than cats and more loyal too.

The first study to actually count the number of cortical neurons in the brains of a number of carnivores, including cats and dogs, has found that dogs possess significantly more of them than cats. As far as dogs and cats go, the study found that dogs have about 530 million cortical neurons while cats have about 250 million. (That compares to 16 billion in the human brain.)

Like dogs, 'così così' about cats. But looking at the figures quoted in original post … wonder why humans can be so idiotic at times.

Wonder how many cortical neurons the humble octopus has? They can be very wiley at times.

A dolphin, a chimpanzee ... be interesting to see.

Dogs are  smarter of course, my mate Chewbarka knows what I'm thinking. Cats are irritating little beasts. Can't stand those people who let them roam free to pee all over your garden.

I love Dogs -- they are much smarter and loyal than any Cat -- and I hate it when irresponsible owners allow their darn Cats to wander and kill all the wildlife and also crap all over my gardens--

Cats are killing machines and we are told they kill 1 million wildlife a day -- why are the owners not MADE to keep them contained and not allow them to run free DAY AND NIGHT as they kill at any time and not because they are hungry --  but there are NO rules to stop this WHY!

A dog can be taught to perform all manner of tricks, and are usually rewarded with food and affection.

Cats are very hard to teach anything to and are extremely stubborn and arrogant, yet they still get fed and receive affection.

On reflection, I guess I know which is cleverer.

We have both a dog and a cat, the cat has a strict curfew and is not alowed out after dark, he has made the odd kill but mostly he brings in those vermin India Minor Birds, but as we can't be sure he will stick to that species he now sports a shiney bell on his collar to warn off the locals.

We have to watch the dog as he tries to play with the Blue Tongue Lizard community and it is not pretty.

They are animals and animals do what animals do.  Cats also rid the community of vermin like domestic mice, rats and other introduced speiies, there is good and bad to be found in most things.

Cats are obviously smarter since they do whatever they want and we still lavish care and attention on them. They just take advantage of humans.

Dogs have masters,cats have attendants.

My cat anticipates me moving to certain areas of the house etc. She seems to be able to read my mind. I taught her how to roll a ping pong ball backwards & frowards to me & we pretend she isthe goalie & has to stop the ball from scoring a goal. She has her indoor toilet & always lets me sleep in & comes when I call her. I have made friends with the 2 year old Rottweiler next door as I love all animals.

I have seen cats do things dogs cannot. I think cats are generally smarter than dogs but dont have the character and personality of a good dog. 

We've always had both cats and dogs.    They're both intelligent in their own ways .  Sometimes far more than humans!   I love the knew that said " dogs have masters" - " cats have slaves".     So very, very true.      Any animal that ' deigns' to give you love and affection in return for doing absolutely nothing all day - now that's clever!

I'm allergic to cats, so it's dogs for me and birds. I think they're all smart in their own way.
