For many years Swedish archeologists have stumbled upon domestic cat remains in the Viking age graves. Most of the graves in this paper come from southern Sweden and Mälaren Valley where many finds have been studied. The questions are how much of the cats is left in the grave material, what kind of grave goods were deposited with the dead, if cats are usually buried either with men or women and what the combinations of all the different animal species that cats were buried with can tell us. The theory in this work is concerning human - animal relations between the vikings and their cats with the weight on antropocentrism. The point of the mentioned theory in this paper is to provide answers to what cats could mean in the viking burial ritual context. 17 grave fields have been analysed for this work with the biggest part of them located in the Mälaren Valley regions (14 grave fields), and 3 in southern Sweden. The result of this study implies that cats in the analysed Mälaren Valley and southern Sweden graves were buried with wealthy people like aristocrats and merchants. They were also seen as exotic pets during their lifetime. The cats were usually buried with other animals like dogs, horses and chickens which all propably had a status of sacral animals during viking age. Cats' remains condition is also brought up as the felines were found either as partial or full/ almost complete skelettons. Analysis results also imply that cats were buried as often with men as with women and there are also rare cases of child burials with these animals.
