The study concerns the analysis and juridical interpretation of the historically shaped normative solutions of the warranty for latent physical defects of animals. Analysis was conducted in selected mixed legal systems of Scots law and legal systems of Louisiana, Quebec, and South Africa. In historical and comparative terms, accurate and unfavorable attempts at legal response to the problem of diseases in live animals have been demonstrated. Hybridization schemes of civil law, which may be adopted in the future, were indicated.
