I'm so sorry to hear about your Sylvia. It is devastating to lose a family member. My beloved cat died 10 days ago, also from a (very aggressive) mammary tumor. I feel comforted thinking she led a full and rich cat life, she was most loved. But I can't help thinking I could have done more. She was misdiagnosed at first, and I bitterly regret not getting a second opinion. But I trusted the, supposed, expertise. I could also have fought for her, opting for additional surgery once I did consult a second vet, and, finally, questioning the vet who claimed there was nothing else to do than end her life. I didn't. I felt she had been through enough, and she was in pain. But I'm racked with guilt. The end was 'humane' - she passed quietly and calmly in my arms. But still, the loss and the grief and the regret. I have read now that these are common feelings pet owners have, especially when illness and decisions about euthanasia are involved. So I think I know how you feel, even if it seems it was more unexpected for you. I hope you can find comfort in caring for your children (and yes, I agree with Marty, showing your children that open grief is natural and healthy will be valuable for them later in life - I never really learned to do this as a child), and in time feel thankful for the time you had with Sylvia. It will be a struggle for me, but once in a while I experience a glimmer of joy when I think about the unconditional love me and kitty shared.
