Cats have claws that can go in and out of there paw and they use them to climb easier. And, actually, dogs can climb, some breeds quite well. They just generally don't need to. It comes down to purpose or reason. Cats adapted to climb to escape danger or to get higher position from which to attack prey. They do not have the developed sense of smell that dogs have, and typically are not as fast nor as distanced runners as dogs. Dogs on the other hand run their prey down, most older breeds have very well developed sense of smell, and tend to nose down whole moving around.
the first sense to be developed is touch
No, they have them, but they're relatively basic.

Yes dogs can sense spirits.
Dogs have a better sense of smell. Smell is a dog's most highly developed sense. Their wet noses dissolve the scent molecules and help them detect smells that mere humans cannot perceive. Many dog experts believe that the canine sense of smell helps dogs 'talk' to each other and help define their relationship. Dogs use their olfactory senses to interpret other dog's pheromones (external chemical messengers) and learn important information regarding gender and receptivity to mating.
