Across PetSmart's top 10 neighbors, no single entity dominates — the similarity scores run from 0.93 down to 0.88 with no sharp drop, a broad shape in which the audience overlaps widely and evenly across a diverse mix of retail and service categories.

The top neighbor is La-Z-Boy at 0.93, a Furniture Store — not another pet retailer. Michaels Stores (0.93) and the Hobbies, Gifts & Crafts category entity (0.91) follow closely, both classified as Hobbies Gifts and Crafts. Best Buy (0.91, Electronics) and ULTA Beauty (0.90, Beauty and Cosmetics) round out the top five. The only neighbor in PetSmart's own subcategory — Pet Supplies and Services — is the category-level entity Pet Supplies & Services at 0.90; Petco, the direct competitor, appears further down at position 10 with a score of 0.80. The remaining top-10 slots go to The Men's Wearhouse (0.89, Mens Apparel), Old Navy (0.89, General Apparel), Red Robin Gourmet Burgers (0.89, QSR), and Regal Entertainment Group (0.88, Movies and Theaters).

The subcategory spread — furniture, crafts, electronics, beauty, apparel, dining, and entertainment all appearing before Petco — signals an audience whose shape is defined by mainstream brick-and-mortar retail habits broadly, not by pet ownership specifically.
