Which animals are included in the PETS category allowed to travel in the cabin?

The correct response specifies the animals that are permitted to travel in the cabin under the PETS category, which focuses on domesticated animals commonly kept as household pets. Cats and dogs are universally recognized as pets allowed in the cabin due to their widespread acceptance and ease of handling during flights. Birds can also be part of this category, as many airlines permit domesticated pet birds on board, provided they comply with specific regulations.

In contrast, rabbits, guinea pigs, and monkeys do not generally qualify for in-cabin travel under the PETS category for most airlines. Rabbits and guinea pigs, while popular pets, are often relegated to travel in cargo due to size, health, and safety regulations. Monkeys are typically restricted due to their status as non-domesticated animals and potential concerns regarding behavior and hygiene in an enclosed space with passengers. Thus, the selection of cats, birds, and dogs aligns with the defined standards for in-cabin travel for pets.
