1. Pet animals of the species listed in Part A of Annex I shall be marked by the implantation of a transponder or by a clearly readable tattoo applied before 3 July 2011. Where the transponder referred to in the first subparagraph does not comply with the technical requirements set out in Annex II, the owner or the authorised person shall provide the means necessary for reading that transponder at the time of any verification of the marking provided for in Article 22(1) and (2), and Article 26, and the identity checks provided for in Article 33 and Article 34(1).
2. Pet animals of the species listed in Part B of Annex I shall be marked or described taking into account the specificities of each species, in such a manner that a link between the pet animal and its corresponding identification document is ensured. In view of the diversity of species listed in Part B of Annex I, the Commission shall be empowered to adopt delegated acts in accordance with Article 39 concerning such species-specific requirements for marking or describing pet animals of those species, taking into account any relevant national requirements.
