Pigs
Pigs are considered to have cognitive abilities and solve problems. They can run through mazes, use tools, and perform complicated social behaviors. Their intelligence is on the same level as that of dogs and some primates.
Squirrels
Notably, many impressive problem-solving abilities have been located in squirrels, especially while working to get food from challenging caches. They remember all the places where food is stored and can devise tactics against predators.
Horses
Horses are among the smartest animals that can stand at command, solve puzzles, and bond well with their human guardians. They can read human emotions and also have excellent spatial relations.
Rats
Rats are very intelligent rodents capable of solving complex problems, memorizing tasks, and engaging in social interactions. They can run mazes, learn from experience, and adapt very strongly to changing environments.
Sea Lions
Sea lions are highly intellectual creatures in terms of problem-solving and learning through imitation. They can perform complex tasks given to them through commands after necessary training. In addition, they show remarkable memory and communication skills.
Baboons
The baboon is one of the most intelligent primates in the world, characterized by its social intelligence and ability to solve problems. They use tools and implement complex social behaviors; they realize who is senior or junior to whom.
Australian Magpies

The Eurasian jay’s ability to problem-solve and reason is, in fact, quite remarkable when planning for the future. Laying up food caches, they remember where they are placed and even have insight into the behavior of other birds.
Border Collies
The Border Collie is considered one of the smartest breeds of dogs in the world. They have significant experience obeying commands, solving problems, and executing complicated tasks.
Pigeons
Pigeons demonstrate a keen sense of homing instinct—they can navigate home over considerable distances. They also display problem-solving skills and have been known to recognize human faces.
Raccoons
The raccoons are an adaptively intelligent species that shows ingenuity by solving problems. They can open latches and run mazes, remembering the solutions.
Gorillas
Gorillas are among the most intellectual primates, displaying advanced cognitive levels, problem-solving abilities, tool use, and complex social behavior. They can be taught sign language and further trained to understand human gestures.
Killer Whales
Advanced hunting strategies of orcas, together with complex forms of communication and sophisticated social structure, are known. They show problem-solving abilities and cultural transmission of behaviors.
Wolves
Wolf intelligence is evident in the complex structures of their social life, communication, and cooperative hunting strategies. They are problem solvers and adaptable.
Cockatoos
