Bottom line

Cats are usually the better fit when you want an in-the-home companion—present in your space with flexible touchpoints. Guinea pigs are usually the better fit when you want a dedicated-setup pet that’s rewarding through steady routines and gentle, day-visible interaction. If “shared living space” is the experience you want, lean cat; if “contained, routine-forward care” sounds ideal, lean guinea pig.

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.
