Does the cat know that its owner loves it?
Cats know that their owners love them. 
1. Although cats do not possess the complex language and abstract thinking abilities of humans, they still have a rich emotional world and social needs. Through behavioral observation and scientific research, we can find that cats can indeed perceive changes in their owners' emotions during interactions.
2. Furthermore, over time, cats gradually develop trust and dependence on their owners. They remember their owner's voice, scent, and movements, and show obvious joy when their owner returns home. This attachment and anticipation towards their owner is a manifestation of the cat's love.
