What's the Buddhist view of fostering a pet?
The difficulty that a practicing Buddhist faces if s/he is a pet owner and a time comes when the pet falls ill and the person decides to “put to sleep” this pet. This is in conflict with the vow of abstaining from killing. After all, animal euthanasia means one is deliberately killing and therefore breaking one of the five precepts. This is creating the karmic cause for one to be born in the hell realm. Even though in the present day we have come to accept the belief that killing with a motivation that is “totally pure” becomes a virtue, it is not so. To take life — one's own or someone else's — is wrong no matter what, something outlined in the first precept which guides us to abstain from killing living beings. So this is the difficulty that a practicing Buddhist faces.
