The German Civil Code (BGB) contains a provision in § 90a BGB that contains regulations concerning animals. The provision is based on the idea that an animal, as a fellow creature, should not be equated with a thing. This is why § 90a p.1 BGB also states that animals are not things. The provision was introduced into the BGB in 1990 by the Act to Improve the Legal Status of Animals in Civil Law (TierVerbG).
