Let me say for openers, I don't know if Helen Keller had a pet. One look at her and you will see a look of contentment on her face and its obvious that she is happy!!! Does it really matter if her pet is a dog or a cat; or if you call a cat a dog or visa-versa? Humm, this sounds a bit familiar to me and after you read the following passage from Paul's letter to the Philippians, I am sure that you will see the parallel right away...
Philippians, Chapter 1
12 Now I desire to have you know, brothers, that the things which happened to me have turned out rather to the progress of the Good News; 13 so that it became evident to the whole palace guard, and to all the rest, that my bonds are in Christ; 14 and that most of the brothers in the Lord, being confident through my bonds, are more abundantly bold to speak the word of God without fear. 15 Some indeed preach Christ even out of envy and strife, and some also out of good will. 16 The former insincerely preach Christ from selfish ambition, thinking that they add affliction to my chains; 17 but the latter out of love, knowing that I am appointed for the defense of the Good News.
18 What does it matter? Only that in every way, whether in pretense or in truth, Christ is proclaimed. I rejoice in this, yes, and will rejoice. 19 For I know that this will turn out to my salvation, through your supplication and the supply of the Spirit of Jesus Christ, 20 according to my earnest expectation and hope, that I will in no way be disappointed, but with all boldness, as always, now also Christ will be magnified in my body, whether by life, or by death. 21 For to me to live is Christ, and to die is gain.

Helen and Paul are both happy; so does it really matter why? Helen has a pet and she cares for it. Paul preached a Gospel that others preached as well- so if they had differing MOTIVES for doing it; so what? No harm, no foul!!! If love is the end result and no sin is occurring.... pet or preach on!!! However, I hope the pet's name is something like Mittens and not something weird like Zander or Diogenes!!!!
