It is spread only between cats through prolonged contact (ex: sharing food bowls). It is feline specific so not contageous to humans, dogs, and other species. If you have cats that are both FeLV+ and - in the same household, vaccinate the negative ones. But it is better to keep them separate to be on safe side. Vets say these cats live 6 months to 2 years, but I have one who's 5 now.
Yes. Like any animal, cats can get viruses (e.g. distemper), bacterial infections, cancer, or mechanical injuries (scratches, broken bones). They are particularly likely to get abscesses (pockets of pus under the skin) if they get a mechanical injury. And cats can, and do, vomit; it is one of the only ways they can clear hairballs, which they get when grooming themselves, but they will also vomit if they are suffering from gastrointestinal illness.
A little more information would help to figure out what symptoms your talking about.

No.
Yes, you can be contagious with chickenpox before symptoms occur.
They are not contagious
Bacterial pneumonia may occur in both dogs and cats. It is highly contagious between dogs but cats cannot catch it from a dog.
While radiation symptoms can occur from a single, prolonged, exposure, the symptoms of radiation are not contagious.
Yes, parotitis is highly contagious. This disease can be contagious for up to 4 days after the person starts showing symptoms.
Not usually, but they can get Rabies, which is contagious if they bite you or if their spit enters through open skin (a cut).
False.NO
FALSE
There does not appear to be a period of time that a cold is least contagious. Scientists believe that a person who has the common cold can be contagious for a few days before their symptoms begin right up until the time when their symptoms subside. This period of time could take up to two weeks. However, the period of time when a cold is most contagious is usually when the symptoms are at their worst, usually 2 to 4 days into the cold.
Gum disease can be painful for a cat and requires a visit to the vet for a cleaning. The condition is not contagious.
Cats can't get chickenpox. Chickenpox is a virus that is only contagious to humans and a few primates.
No. It is a set of neurologic symptoms which exist long after polio, itself, is experienced by the sufferer.
