In recent years, Heidegger's thought has been attacked by so-called animal philosophy with the accusation that it leaves no room for animal life, and even devalues it. The present study takes a look at Heidegger's entire work in order to present a diametrically opposed design. For this purpose, the difference Heidegger claims to exist between man and animal is located and interpreted within the frame of reference of ontological difference. In this way, it can be shown that animals do not differ from humans because they lack something, but because they are endowed with a fundamentally different mode of being. Starting from this observation, the author devotes herself to exploring the mode of being that is "life" and shows that with Heidegger it is possible to speak about the living without degrading it or - which would be equally mistaken - subjecting it to a romanticizing glorification. The result is an approach to animal life that takes its otherness into account.
