Cats

Vocal Clues

Cats can be very vocal, especially when they’re happy. Vocal kitties may have long conversations with you, and the pitch of their meow will allude to how they are feeling.
A high-pitched meow is a content cat, while a low-pitched meow may indicate an unhappy or annoyed kitty. That ""prrrrupttt!"" sound many cats make, is also a good indication of a happy cat.
While purring is not always a sure-fire sign of a cheerful cat, for the most part, it can be an indication of feline contentment or even bliss.

Social Sleeping

While cats may sleep more when depressed, their sleep locations can be an indication of happiness. If your kitty sleeps with other cats or chooses you as a bed-buddy – this indicates happy relationships.

Playful Behaviour

Play is a great indication of happiness, and your kitty will play with other pets and humans that they like or trust.
From exuberant sprints and kitty wrestling matches to calm paw patting of the features, these playful activities indicate a happy cat.
