Animal Welfare & Seller Responsibilities

Bask cares about the welfare of the animals advertised here. This page sets out our welfare stance and the legal responsibilities that fall on sellers.

Our welfare commitment

We expect everyone using Bask to meet the five welfare needs of the animals in their care (a suitable environment and diet, the ability to behave normally, appropriate company, and protection from pain, suffering, injury and disease), in line with the Animal Welfare Act 2006 (England and Wales), the Animal Health and Welfare (Scotland) Act 2006 and the Welfare of Animals Act (Northern Ireland) 2011.

Prohibited morphs

Bask applies the Deleterious Gene Policy published by REPTA, the Reptile and Exotic Pet Trade Association, and endorsed by the British Veterinary Zoological Society. Some morphs are linked to structural, neurological, metabolic or fatal hereditary conditions, and there is no ethical case for breeding or selling them when healthy, attractive alternatives exist. The morphs on REPTA's prohibited list cannot be listed on Bask. A listing that carries one is refused when it is saved; a listing that was live before a morph joined the list is withdrawn, the seller is emailed, and no strike is recorded.

The prohibited list as REPTA publish it (reviewed with them every six months):

  • Spider royal python: an inherited inner-ear anomaly that presents as moderate to severe wobble.
  • Super Champagne and Super Hidden Gene Woma royal pythons: lethal. The animal dies in the egg or within hours of hatching.
  • Champagne × Hidden Gene Woma royal python: often severe neurological issues.
  • Super Black Pastel and Super Cinnamon royal pythons: a high likelihood of an underdeveloped lower jaw and spinal or tail kinking.
  • Super Motley and Super Jungle boa constrictors: metabolic issues, with loss of muscle tone, poor digestion and a heavily shortened life.
  • Jaguar carpet python: neurological issues, including wobble and an inability to self-right.
  • Skull Face western hognose: a high likelihood of cranial, jaw, eye and nasal malformation.
  • Super Cappuccino and Super Lilly White crested geckos: a high likelihood of cranial, spinal and limb defects.
  • Enigma leopard gecko: neurological issues affecting balance, coordination and cognition.
  • Lemon Frost leopard gecko: a high likelihood of skin tumours (iridophoromas).
  • Super White Out African fat-tailed gecko: lethal.
  • Silkback bearded dragon: scaleless, so fragile skin, burns, dehydration, and no protection from UV-B.

An animal that is already alive deserves a good home, and keeping one is not a breach of anything. The rule is that it cannot be advertised for sale here.

Morphs with a welfare note

Some other morphs are linked to milder or less certain hereditary conditions: the single-copy champagne and woma royals, super sable, super spotnose, desert, caramel albino, the super lesser and super butter royals, and the stargazer corn snake. We allow these morphs, but to help buyers make informed decisions we automatically display a welfare note on any listing that carries one. We encourage buyers to research the morph and ask the seller about the specific animal. We may remove listings that raise a genuine welfare concern.

Breeding guidance

Some morphs are healthy in a single copy but produce prohibited offspring when paired to a similar line: a champagne to another champagne, a cinnamon to a black pastel, a leatherback to another leatherback. REPTA ask sellers to give buyers of these animals written guidance and to keep a record that it was given. Bask shows the guidance on the listing itself, and a buyer confirms they have read it before their enquiry is sent; that confirmation is kept in the seller's conversation as the record.

Age of buyers

It is an offence to sell an animal to anyone you have reasonable cause to believe is under 16. Bask goes further: accounts are for over-18s, and the sale is to the account holder, who takes legal responsibility for the animal. The Animal Welfare Act already makes the parent or guardian of an under-16 responsible for an animal the child owns, so this is the law's own model, not ours. A young keeper is welcome to browse and choose alongside a parent or guardian; the parent buys, collects, and is the person the seller deals with.

When a seller needs a licence

If you sell animals "as pets in the course of a business", you may need an animal-activities licence from your local authority (in England, Scotland and Wales). Whether you count as a business depends on factors such as whether you sell to make a profit and how often and how much you sell. HM Revenue & Customs' "badges of trade" and the £1,000 trading-income guide are useful starting points. Genuine hobbyists selling occasional surplus are usually out of scope, but the position is judged case by case.

This responsibility is the seller's, not Bask's. If you are unsure, check with your local authority. Northern Ireland has different rules, so contact DAERA there. We provide this as general information, not legal advice.
