If you feel like your cat has fallen out of love with you, you're probably not imagining things.
Cats are very touchy creatures; any unacceptable behavior upsets them.
Why a cat may fall out of love with its owner
First and foremost, the cat will certainly fall out of love with you if you punish her so harshly.
Secondly, your pet may stop loving you due to lack of attention. Lack of affection and joint games can drive the cat into deep depression.
Thirdly, the cat will most likely fall out of love with you during your long absence.
Contrary to popular belief, cats miss their owners just as much as dogs.
Also, the cat may stop loving you for moving to a new home. Any, even minor changes cause stress in cats, let alone moving.
