Why do individual humans have such unique faces while animals have faces that are all similar? Is this purely perception? Are we actually just as similar looking to each other as the animals are?

Not all animals use facial identification. An ant uses pheromones. A dog sniffs the anal glands of other dogs, which contains a unique scent. Whales have unique names that they use when singing. Birds have unique calls, etc.

What he said, plus… human brains are very specialized in picking out other human faces.

Which is why even very advanced androids (robotics that look like people) look “off”.

We have a very keen sense for the differences and similarities in human faces. Less so in animals.

Animals do look different, too, we just don’t spent enough time observing them to notice the differences, and we’re just less attuned to differences of different species. But if you were a farmer or zookeeper and regularly interacted with a group of animals you’d learn the differences in their faces.

Combination of us making great use of our face for communication and identifiation and our brain being specialized in picking them out. Also I read at some point that it is more difficult spotting differences in “foreign” faces but one does get better when spending more time with said people.

It is just perception.

This is why people sometimes say that all <insert race> look the same. We are better able to distinguish the features of individuals that we are surrounded by. Caucasians will have different colors of hair and eyes and focus on that. African Americans mostly have dark hair and eyes but a lot of different shades of skin and facial features.

There have been studies where people were shown different African American faces. Those who grew up in places with a higher African American population (and those who watched a lot of NBA basketball) were better able to distinguish individuals.

Animals don’t as much go by face but often have other identifiers (spots/stripes/smells) that help them to distinguish individuals and for them it as just as easy to tell Joe apart from Bob.
