Sonya the cat proved she can most definitely hold a grudge, after she reacted to an incident in a way that left her owner speechless.
Completely by accident, Sonya's owner stepped on her feline friend as she was going down the stairs. Little did she know, she would be in for a surprise of her own!
The unfortunate incident
The beautiful green-eyed cat looked so shocked and hurt by the incident, she immediately began planning her revenge.
"Meow, meow, meow", she can be seen furiously writing in her diary. Then her owner realises what's going on.
Unexpected revenge
The clever cat's ritual is designed to make her owner feel the exact same pain she did - and the result had millions in stitches.
Despite the cat's reaction, various animal behaviour experts agree that cats don't possess the cognitive ability to hold grudges.
Such emotions are complex and require the ability to reflect on the past and plan future actions.
