PetSmart is the world's largest pet supply and services retailer, offering a wide variety of products for pets, including dogs, cats, birds, fish, amphibians, reptiles, and small animals. Customers appreciate the friendly staff and the quick in-store pickup option for online orders. Many enjoy shopping at PetSmart for fish and decorations, highlighting the helpfulness of employees. However, some reviews mention that certain locations have become poorly stocked and messy over the years, with concerns about cleanliness and inadequate staffing during busy times. Although one location has an older look, customers still find it reasonably clean, and some express hope for improvements in service quality, especially regarding veterinary services from Banfield Pet Hospital. Overall, while experiences can vary, PetSmart continues to be a popular choice for pet owners looking for a variety of products and services.
