Would a LaPerm be more people-focused than a Selkirk Rex?

Start with their breed histories. LaPerms originated from a barn cat mutation and tend to be active, curious, and moderately people-focused-they enjoy your company but aren't glued to you. Selkirk Rexes were developed from a Persian cross and are known for being calm, affectionate, and often more attached to their humans, seeking laps and physical closeness.

So no, a LaPerm is usually not more people-focused than a Selkirk Rex. If you want a cat that follows you around and demands attention, pick the Selkirk. If you prefer an independent but friendly companion, the LaPerm fits better.
