Evidence of animal sentience is everywhere. Did you know that turkeys like to sing along to their favorite tunes? Or that hens talk to their babies before they are even born? Or that fish in fact feel pain akin to that of mammals?
These top ten amazing facts about animal sentience are sure to make you love and respect animals for how incredible they truly are (even more than you already do!).
1. Cows Get Excited When They Solve Problems

In 2004, Cambridge University research demonstrated that young heifers were enthusiastic and upbeat when they overcame problems and were able to reap a food reward. Their heart rate increased, and many of them bucked, jumped, or kicked in excitement when they solved the problem. When the same food reward was simply placed in the pen with them, none of the cows showed any signs of excitement whatsoever, proving that it was the problem solving and not just the reward which got them all jumping about!
2. Sheep Respond to Facial Expressions

Sheep have an amazing ability to remember more than 50 individual faces from their flock even after two years of being separated. They also recognize and react to changing facial expressions of both sheep and humans. They are more relaxed when greeted by a smiling face and become anxious when they see another sheep in distress.

Hens and their offspring begin communicating before the chicks are even born, with the mother hen softly clucking to her babies, and the little chicks peeping back from inside their shells to let her know they will soon be hatching.

Octopi are able to survey their environment and work out the best way of disguising themselves. Mimic octopi alter their body shape to replicate other animals, whilst others murky the water with black ink so that they can slip away, and some have even been known to pick up shells, rocks and coconuts to disguise themselves. They are extremely perceptive and can analyze the environment and plan out a complex attack or getaway method using these tools.

Vixens have been known to get assistance rearing their cubs by a non-breeding sister or daughter. These ‘aunts’ gain valuable parenting experience which in turn helps them to raise their own successful litter the following season.

Pigs are very family-orientated animals and within moments of leaving the womb, piglets head straight to their mother’s face where they rub noses and officially meet for the first time. After that, whenever mom calls out, the piglets come a runnin’.

Rabbits (as well as other burrowing animals) are capable of constructing huge labyrinth-style underground systems which are also known as warrens. These warrens have specific passages for eating, sleeping, storing food, entry and exit, and even for emergency escape from predators.

Everyone agrees that other mammals feel pain just like humans do, but there is a common misconception that fish do not. In fact, fish have complex nervous systems and pain receptors which trigger the release of endorphins in response to physical injury. Pain is an evolutionary survival mechanism as all animals need to be able to respond to physical dangers whether in the water or on dry land.
