Why do cats purr?

they pur when theyare happy, comfortable, or at ease. its like their way of saying “hey that feels good!”

ahhahahah ur adorable

hahahaa.. thanks

Cats purr when they are very pleased. Cats also purr when they are getting ready to stalk their prey (or toy if the cat is domestic). They purr when they are extremely frightened (lions roar which is an effect if purring) and they purr when they see food. :P

but what happenes when a cat pursrs and wags its tail (as it is a sign of discomfort)

Yup! My poor kitty hates getting his ears and teeth cleaned, and purs the entire time.

laughs this is actually a cute question in terms of purring. my male, freckles, purrs the second you look at him, when you give him food, water, loving, and he even purrs when i clean his litter boxes! my female, mischief, when she was having her kittens (all three litters) she tended to purr to relax her muscles, and let her babies know where she was so they could turn around and nurse from her. purring is normally for happiness and relaxation :) and its always fun to watch them purr, because they do the cutest things. mine stretch (curls their toes right up XD), kneed whatever their paws can touch (usually my arms =_=) and they fall right on their sides nad sleep. its adorable really
