Yes they can. Cat's can sense the same way a dog does and even more then a dog actually. Cats can sense pain and they also can feel other cats pain as in sympathy.
There is no evidence that they can "sense: each other. However, dogs and cats have better hearing than we do. So they can potentially hear another animal moving on the other side of a wall.
Yes. When a cat is about to have kittens, there is a certain smell, and other cats can smell this.
Tigers and other cats have a great sense of smell I'm not sure how far they can smell but I think that it is at least 1 mile.
Nervous system causes the person to sense pain.
Only when thier owners are in pain or in a bad mood will cats rub on you and kneed. If you crie watch your cat and she/he will jumpin your lap. the body language of a cat will tell you the cat is there for you. somthimes cats will show you the answers to questions.

Yes, they sense it. Cats can sense what you are feeling and what you are thinking. They understand their owners.
Cats mostly rely on hearing, smelling, taste, and sight.

This makes no sense.
they do or they wouldn't smell you
As cats are carnivores, foods such as meat will naturally smell good to cats. Fish and other strong smelling foods will also attract a cat. Cats have an acute sense of smell, and generally will be attracted to foods that are stronger-smelling than others.
