DR SEIDEL ADAPTATION COLLAR FOR CATS is a state-of-the-art, multi-ingredient preparation belonging to the group of behavioural aids. It has a calming effect on cats. It contains a composition of natural substances influencing behaviour of animals, similarly as cat pheromones do. The composition corresponds to the mixture which has been known since 1996, disclosed in European Patent EP0724832. The use of the collar during behavioural therapy significantly enhances the process. It gives the cat a sense of security, fosters learning and quick adaptation to new challenges.
