Let's say you are a vegetarian who does not eat meat for ideological reasons (e.g. you recognize their right to live; you do not want them to suffer). And you are dealing with the following situation: Cats living in the wild come to your garden and demand feeding. You feed them with different delicacies since, as a rule, you love animals and think it's your duty. As a reward, the cats bring you and put in front of the garden door gifts - mice, voles, birds killed by them. It is possible that you contribute to the death of other animals. What should you do? Won’t you feed the cats anymore?
