Just like dogs, cats drool. My dog drooled when it was expecting a treat. If you do this on a regular basis they get a reflex action anticipating the treat. Cats sense that you are going to give it a treat and it purrs, drooling awaiting the treat. I had a strange cat that did this with caramel candy. The cat liked caramel candy and at a certain time of day the cat would show up wanting the candy. Purring and drooling. It was a special habit.
Cats have scent glands in their mouths so when they are doing things with their mouths open it's because they are scenting something using their mouth rather than nose.
because they r happy and relaxed
It's their way of showing affection.
I heard that cats rub their heads against you to get their scent all over you. It's a sign of ownership; they are saying, "This is my human."
They lick your hand and rub their head up against your hands
My cats show their affection when they rub up against my leg
the purr when they are relaxed and when the rub against ur legs that means they want luvin
There are many ways cats respond to stimuli. Depending on the cat, they might purr, meow, or rub up against you.
The cat is "marking" you with it's scent, especially if you were near another cat or dog.
When cats rub against someone leg they are marking their teritory; so when other cats come along they know that you belong to another cat and then they will rub against you to mark their teritory and so it goes on.Cats also rub your legs to show affection or because they are hungry. My female boss cat only does this when I am standing close to her food bowl or I have lunch meat in hand.
Cats will rub their backs or bodies on you when being petted to transfer its scent onto you.
Largely it is to add their scent to the scent of that spot, to take ownership of a place that smells particularly nice to them.
They usually lick where they are dirty or rub up against something to take the dirt off. Dogs are usually not as hygienic as cats.
If you rub pyrite against steel sparks would fly.
Its just in a cats nature, her way of showing her love and loyalty to u :-)
