As an adoptive parent of animals I insist on the right to have them treated as dependents.
It has been our choice, my wife's and mine, not to have children. Our pets become our children and I will no longer hang my head in shame because I choose to nurture helpless animals.
By every standard, other than that pesky species thing, my animals are my family and by many indicators my love for my animals is far superior to many human-human family units.
In so far as my animals are insured, fed, and provided shelter they qualify as dependents.
My entire tax paying, insurance paying, and mortgage paying life has supported my communities. I paid for schools, hospitals, institutions, bridges and roads. All to support human-human family units.
I will be collecting my past tax refunds that will include all my animal dependents promptly.
