There's no denying that most animals are cute (unless they have big pointy teeth and want to eat you), but pets are even cuter - pets are safe, cuddly, well-meaning and harmless, of course they are, right?
You of course take their unconditional love for granted, safe in the fact that they would never do anything to upset or harm you. You have a common bond, right? Something that a pet and it's owner share.
Pets and animals may be part of your extended family but they also have their own agenda and if you are not part of that then prepare for some physical and emotional pain as they relay this to you in the only way they can.
Also, it's not just limited to humans, pets have issues with other pets and animals too and they will hold no punches if they are not happy with the situation they find themselves in.
The pay-off (and there always is one) is that the results of this behavior makes for some perfect internet fodder as the hilarious results below show.
