Mexico City took a significant step in terms of animal protection. The capital’s Congress approved a legal reform that prohibits the physical display of dogs and cats in cages, showcases, or other spaces where their movement is restricted or they are kept as objects of exhibition.
The measure aims to improve the conditions of sale and adoption of companion animals and prevent practices that harm their welfare.
A reform focused on welfare
The initiative, approved by the Animal Welfare Commission of the local Congress, establishes that dogs and cats for sale cannot be displayed in narrow or closed spaces that cause them stress, fear, or anxiety, thus protecting their physical and emotional health.
From now on, the sale and adoption of these animals must be carried out only by appointment, and a veterinary zootechnician must be present throughout the process. The animals must remain in safe areas with adequate food, water, and protection.
Mandatory requirements and care
The regulation sets clear conditions for commercialization and adoption:
- Only sterilized and dewormed dogs and cats may be sold.
- A health and origin certificate will be provided.
- Buyers will receive complete information about care and behavior.
- If the adoption is not finalized, the animal must be returned within a specific period with a reinstatement fee.
The Environmental and Territorial Planning Prosecutor’s Office (PAOT) will be the authority responsible for imposing sanctions. Establishments that do not comply may receive fines ranging from 150 to 3,000 Units of Measurement and Update (UMA), equivalent to approximately $16,900 to $339,000 Mexican pesos.
The prohibition will come into effect 365 calendar days after its publication in the Official Gazette of Mexico City, during which time the authorities must define the minimum space and protocol guidelines to apply the regulation.

Benefits of responsible adoption
The reform also aims to promote responsible adoption as an alternative to purchasing animals:
- Improves the pet’s quality of life and strengthens the emotional bond with its adopter.
- Helps reduce the number of dogs and cats in shelters and supports the work of animal protection organizations.
- Encourages responsibility in children by caring for another living being, in addition to improving their health by reducing the frequency of illnesses.
- Assists people in difficult times by providing companionship and emotional support.
- Cats offer independence and affection, while dogs provide unconditional love and promote a more active life.
A cultural shift towards animal respect
The reform marks a profound cultural change: to stop seeing animals as objects of exhibition and recognize them as living beings with rights and needs. Society is called to promote responsible adoption, ensuring that every dog or cat lives in a permanent, happy, and safe environment.
The prohibition of displaying dogs and cats in showcases and cages in Mexico City is a historic advance in animal welfare. With clear requirements, defined sanctions, and a focus on responsible adoption, the Mexican capital positions itself as a leader in the protection of companion animals.
