Cane, I am so sorry for your loss, I can't even imagine. Losing a cat or dog that has been a part of your life for 10-15 years is hard enough, a pet that has been part of your family for over 30 years, must be so much worse.
Dear Cane, there is little I can say except I am sorry for your loss. Those creatures in our care do attach themselves deeply in our heart. It should give you peace to know that you did everything you could to make her life a good one and her passing easy. Love and hugs!
