Be careful that you dont become desensitized to your fellow human being. Hate their sins but endevour to save them. As for animals, they respond to what they observe from you, it would be the same if you have kids, you can mould them in your image, but the animals who cannot sin will always be in union with natural and divine law, humans will not have that virtue. You probably like pets because they have this union with divine and natural law, but remember that you are not in union with those laws becaues of your sin, and know that only other humans can save you, because humans alone have the solution to sin, which is grace and the sacraments.
but someone told me to get a dog, but i would rather keep my cold aloofness. i have sympathy for other people more than they know, but just dont have the emotional tides that go with it since i am not connected to other people, and i dont want these tides either, because imo it would take me away from God and into the world which i am called to reject. so i dont want no pets polluting my mind with emotional mush.
