In addition to Richard's statement about unconditional love, I also believe that pets contribute to our own health and well-being. I read somewhere that those with pets have lower blood pressure and live longer. Having a pet gives me something else besides myself to look after. Look at all the pets that visit long term care homes; the benefits are plenty. Residents are happier and it perhaps brings back memories of dogs or cats they used to have.

Why do people need a purpose to have pets and why do pets need to have a purpose to be cared for??? They are all God's creatures and so should be loved unconditionally just like us hoomans.
