The Swedish regulations in force on animal protection matters - regulations on destination breeding, experimental animal housing and ethical pre-testing - are a solid base for controlled and adopted experimental animal use in relation to the political attitudes prevailing towards these questions in Sweden. Certain and by no means small or unsignificant groups of the population are, however, still very critical of the structure of our regulations as well as the application thereof, and of the experimental animal use on the whole. This is something that Sweden has in common with several other countries. In an international comparison, however, the situation for the experimental animals in Sweden is likely to be quite good.
