If you're referring to which guardian cat is most frequently associated with Sailor Mercury, it would be Luna. Though Sailor Moon/Usagi owns Luna and lives with her, Luna is responsible for finding and activating the powers of Sailors Moon, Mercury, Mars, and Jupiter, and as such, has taken on guardianship for all of them.
Artemis discovered Sailor Venus first, and since she was active as Sailor V prior to joining the other Sailors, lives with Artemis at her own home. Artemis is generally as much of a guardian to the other Inner Senshi as Luna is, but the other girls seem closer with Luna than they do with Artemis.
