Hmmmm. I wouldn't say animals are our neighbor in the way Jesus taught with the parable about the Good Samaritan. But we have a priestly role where creation is concerned. Creation fell because of Adam's sin. Creation will be redeemed along with and partly because of mankind's redemption by Christ.
I don't think those verses figure into it particularly. Wisdom especially has to be interpreted within context. Though I will say that verse in Eccl does add to the point that "we are all in this together" where both fall and redemption are concerned. But to read too much into it would lead to error. The Proverb talks about what kind of people we ought to be. We should be caring, taking care of our responsibilities, properly stewarding, and not cruel. Again, we become what we practice. That is part of how "works" figure into salvation. If we are loving people, we become more like Christ in our very heart and soul. If on the other hand we delight in being cruel, we twist and pervert our heart and soul to become more like Satan.
