Buying Guide: What To Consider When Choosing A Pet Door

- Installation difficulty: Some options are DIY-friendly with basic tools, while large wall installations may require professional help.
- Durability and materials: ABS or durable plastics work well for light to moderate use; steel frames and reinforced flaps suit higher-traffic homes and larger pets.
