Bottom line

Cats make the most sense if you want relationship-first companionship in your living space—direct bonding and real check-in moments. Mice make the most sense if you want a compact, enclosure-centered experience where the reward is watching behavior and group dynamics. If you want your pet to engage with you, go cat; if you want something engaging to observe in a contained setup, go mice.

See which one fits your situation

Comparing helps with tradeoffs. If you want a more “real life” answer, start from your context (apartment, busy schedule, quiet home, allergies, kids, etc.) and see which pets tend to fit best.
