Dogs and cats are not personality variants of the same psychological type. They are the products of radically different evolutionary strategies, and those strategies produce radically different emotional architectures.
Dogs evolved to read human social cues with extraordinary precision because their ancestors' survival depended on navigating the human social world. Cats took a different path. They tolerated humans. They co-existed with them. Over millennia, they adapted to live alongside us without ever abandoning the fundamental operating system that evolution had spent millions of years writing: the solitary predator's manual.
A 2019 study by Kristyn Vitale and colleagues at Oregon State University, published in Current Biology, tested whether cats show secure base effects similar to those documented in dogs and human infants. In a modified Strange Situation protocol, 70 cats and kittens were briefly separated from their owners and then reunited.
Approximately 65% of cats showed secure attachment patterns — returning to balanced exploration after reunion rather than displaying anxious or avoidant responses.
