Here's why:
* Stress Purring: Cats sometimes purr when they are stressed or in pain. This is a way for them to self-soothe and release endorphins. It's like a cat's version of a coping mechanism.
* Other Signs: Look for other clues besides the purr to decipher your cat's mood. For example, dilated pupils, flattened ears, a twitching tail, or hissing are all signs of potential anger or anxiety.
So, if your cat is purring but also displaying these other signs, they might be experiencing stress rather than happiness.
It's important to remember that every cat is an individual, and their behavior can vary. If you're unsure about your cat's mood, observe them carefully and consult with a veterinarian if you have concerns.
