There isn’t solid scientific evidence that a higher IQ reliably predicts whether someone will prefer cats or dogs. Intelligence scores are influenced by education, testing context, and many other factors, while pet preference is shaped by lifestyle, personality, past experiences, housing rules, allergies, and daily schedule. When studies do find differences between cat and dog owners, the pattern usually points more to personality and environment than to “smarter equals cats” or “smarter equals dogs.”
Some survey-based studies report small average differences between self-identified “cat people” and “dog people” on certain traits. Cat owners are sometimes associated with higher openness to experience and more independent routines, while dog owners are often linked with higher extraversion and more social activity. In a few datasets, cat owners have slightly higher average test scores, but those results are typically modest and can reflect confounding factors such as urban living, working hours, income, education level, or the kinds of jobs people hold—variables that also influence which pet fits their life.
Dogs generally require more structured daily involvement (walks, training, frequent engagement), which can be a better match for people who enjoy routine and outdoor activity. Cats often adapt well to smaller spaces and may be easier to manage with a busy schedule, which can be attractive to people with long workdays or limited flexibility. Those realities can align with different life stages and living situations rather than raw cognitive ability.
If the goal is finding the “right” pet, focusing on temperament, time available, and home setup is more practical than comparing intelligence levels.

Interacting with pets can support well-being by lowering stress, encouraging routine, and increasing social connection or activity. Those benefits may indirectly help cognitive health, but they don’t “raise IQ” in a straightforward way.
