There isn’t a definitive, universal rule that people with higher IQs prefer cats over dogs (or the other way around). Some surveys and observational studies have reported small tendencies—often suggesting cat owners score slightly higher on certain cognitive or academic measures—but the differences are usually modest and heavily influenced by lifestyle, personality, and environment.
Cats are often associated with independence and quieter households, which can align with certain traits that also correlate with higher scores on some tests (like introversion, preference for solitary activities, or spending more time reading). In some research, cat ownership has also been linked with higher levels of education, which can get blurred in popular summaries as “higher IQ.”
Dog owners may be more likely to have routines that involve frequent outdoor activity and social interaction. Those traits can be connected to different kinds of strengths—like communication, teamwork, and emotional intelligence—that aren’t fully captured by a single IQ score. Plus, many high-achieving people prefer dogs simply because they enjoy training, companionship, and the structure that comes with dog ownership.
Pet preference tends to track more closely with daily life than with raw intellect: housing rules, work schedule, travel frequency, allergies, noise tolerance, and how much time someone wants to devote to direct pet interaction. A person’s “best” pet match is usually the one that fits their routine and temperament, not their test score.

For Cats vs Dogs: Is IQ Linked to Pet Preference?, the best answer depends on fit, material, care instructions, and how the product will be used day to day.
Pet ownership doesn’t reliably increase IQ, but it can support habits linked to well-being—like routine, stress reduction, and social connection. Any cognitive effects are more likely indirect (through lifestyle and mental health) than a direct boost to intelligence.
