The short answer: yes, cat saliva is harmful to humans. Cats host several types of bacteria in their mouth, including Pasteurella multocida, Staphylococcus, E-coli, and Salmonella, which all have zoonotic potential (able to infect humans).
Cats carry bacteria in their mouths, which can lead to local or systemic infection if a cat licks an open wound. Immunocompromised people are most at risk. Acquiring a disease from your cat is very rare, but to be safe, don't let your cat lick your face or any cuts on your skin.
While it is unlikely to cause any serious harm, it is important to remember that cats can carry bacteria in their mouths that can make humans sick. What is this? So it is best to avoid eating anything that a cat has had contact with, just to be safe.
You just need to avoid mouth-to-mouth contact, and put that stockpile of anti-bacterial gel to good use. Cats pick up the same bacteria when they clean themselves, too, so letting your cat lick your mouth, nose or eyes is not recommended.
Furthermore, cat saliva contains compounds that can aid the healing process. A few compounds contained in cat saliva such as opiorphin, peroxidase, lactoferrin, and thrombospondin act as a pain reliever and antibacterial.
However, it is not advised that you kiss a cat who is sick, nor do I recommend kissing cats on the lips. Many diseases can be passed on from cats to humans (zoonotic). Cats and humans can become infected with common bacteria such as Pasteurella, staphylococcus, E-Coli and salmonella. All of which are highly contagious.
As a public service to our readers, it's probably okay for you to lick your own wounds (though that's gross), but please never allow your cat to lick your open sores. Using your feline as your primary wound care specialist can lead to a terrible condition called cat scratch disease.
Chris Miller, AtlasVet DC: The good news is that drinking after your cat is very unlikely to cause any significant health concerns. Cats can be finicky drinkers, but the amount one cat drinks compared to another can be highly variable.
Many kinds of bacteria (germs) called Capnocytophaga live in the mouths of dogs and cats. These germs do not make dogs or cats sick. Rarely, Capnocytophaga germs can spread to people through bites, scratches, or close contact from a dog or cat and may cause illness, including sepsis.
*Discourage your pet from licking your face.
Capnocytophaga canimorsus and Pasteurella multocida are two bacterial infections that can cause severe disease in these two high-risk groups. In addition, pets frequently lick their anus and can possibly transmit fecal pathogens to you when they lick your mouth.
Cats are biologically programmed not to drink water which is near their food or near their toileting area - this is thought to be their instinctive avoidance of contaminating their water with potential sources of bacteria.
However, I would not recommend drinking the milk a stray cat licked. Strays carry many bacteria and fecal viruses on them, while boiling it should kill most of the bacteria, you should avoid drinking that milk.
This suggests that cats carry a heavy bacterial load in their mouths. Since human beings often bite the inside of their mouths, transferring bacteria from a cat's mouth to the site of an oral wound is not a good idea. Give your cat her own plate and fork.
Ziskin says that cats' “gentle 'love' nibbles or light licks” are a way of showing affection, and that some cats even give kisses! She says that your pet may also show affection by purring, nuzzling up to you, or rubbing their head against your body.
Signs of Affection

A recent study by researchers at the Georgia Institute of Technology in Atlanta, Georgia, shed new light on how cats' scratchy tongues enable them to keep themselves so clean: they're covered with hundreds of sharp, tiny hooks called filiform papillae.
It's especially important for young kids, older adults, and people with weakened immune systems to wash hands regularly because they're more likely to get seriously sick from germs animals can carry. In a perfect world, you would wash your hands after every time you touch your pet.
The chances of people getting Giardia infection from dogs or cats are low. The type of Giardia that infects humans is not usually the same type that infects dogs and cats.
No, they do carry bacteria and some diseases like a dog does. Just throw it away.
Cats with dental infections, inflammation in the mouth or gastrointestinal disease may avoid drinking water due to the discomfort it causes them. Cats with underlying health issues may be more likely to become dehydrated, especially those with kidney issues, hyperthyroidism, some cancers and diabetes.
In Islamic tradition, cats are admired for their cleanliness. They are thought to be ritually clean, and are thus allowed to enter homes and even mosques, including Masjid al-Haram.
To show affection
Licking is not only a grooming mechanism but also a way cats show that they love you. Your cat is creating a social bond by licking you, other cats, or pets. This sign of affection may stem from kittenhood when your cat's mother licked them to groom them and show care and affection.
Purring. In many cases, soft, gentle purrs signal your cat's satisfaction with the world, providing an audible sign of her contentment. But purring doesn't always indicate happiness; some cats also purr when they are hungry or stressed.
