Petco's nearest audiences are a mix of classic rock acts, genre TV, and gaming hardware — not other pet or home brands. The top 10 neighbors span a narrow similarity band (0.70 down to 0.66), consistent with the flat shape: no single neighbor dominates, and the cluster has a recognizable character rather than a clear anchor.
Comic Book Men leads at 0.70, followed closely by Pink Floyd at 0.70 and Katey Sagal at 0.70. Robert Kirkman (0.68) and Lucifer (0.68) round out the top five. By subcategory, the top 10 breaks down as: two TV Shows (Comic Book Men, Lucifer), one Musicians and Bands (Pink Floyd), one Actors (Katey Sagal), one Authors (Robert Kirkman), two Technology brands (TCL USA at 0.67, Logitech G at 0.67), one TV Channel (Animal Planet at 0.67), one Technology brand (EVGA at 0.67), and one Beverages brand (Rockstar Energy Drink at 0.66). No other Home brands appear in the top 10 — Petco's own subcategory is entirely absent from its nearest neighbors. The dominant thread running through the set is a geek-culture and hard-rock adjacency: comic book media, genre drama, classic rock, and PC gaming hardware all share the same audience shape as a pet retail social account.
The flat distribution across these subcategories suggests Petco's social audience is defined less by category affinity and more by a specific demographic cross-section that happens to index across entertainment, music, and tech simultaneously.
