A cat appears
We are not really sure if cats love or hate Christmas, it seems like they themselves have mixed emotions on the subject. On one hand, cats clearly love playing with the ornaments on trees, but on the other hand, they hate all holiday cheer. They really should make up their mind on where they stand.
This person thought to immortalize their cat by putting them on a sweater and showing them jumping out of nowhere from behind a tree. It seems that they have a cat of their own and this sort of thing has happened so much that they just had to make a sweater out of it.
