To run a business selling pet animals, you need a licence from your local council. This includes all commercial selling of pet animals, including pet shops and businesses selling animals over the internet.
As an applicant for a pet shop licence, you must not be disqualified by a court of law from running a pet shop business. You must also ensure that:
Animals will be kept in suitable accommodation, for example in regards to temperature, size, lighting, ventilation and cleanliness
Adequate food and drink will be provided to the animals and they will be visited at suitable intervals
Any mammals will not be sold when they are too young
Steps will be taken to prevent disease spreading among the animals
Adequate fire and emergency provisions will be in place
