We carry with us a certain amount of guilt when we own a pet. Because, when we harness our dogs and cage small animals, we deprive them of their freedom. We would feel especially guilty about caging a bird that flies freely through the sky. But we wish to have pets without feeling guilty about it. So I have prepared an ideal space for birds in a cage. The birds will be happy. Anyway, we are now free from guilt. Goodbye, guilt. We are one step closer to utopia.
