Condolences on your loss. I lost 3 of a litter of 5 this spring, and they had an experienced Momma to care for them. It is very sad to lose a sweet baby.
Initially, I talked to my dh about not fostering kittens anymore. I thought it was too hard on me and the kids (age 6; 9; 16). DH said kids have lived on farms for years, and have seen death up close, and they turned out just fine. Then I spoke to a co-worker who's 4 y/o son is struggling to understand what death is, and I realized that at least my kids really understand death, from losing 5 kittens since last summer.
I am not minimizing the pain they feel. But understand, that someday in your children's lives, they will lose another beloved life, whether a family member or beloved pet. How you teach them to deal with the loss of this tiny kitten helps them handle the other crisis they will inevitably face.
I tend to intellectualize, or try to make sense of things. But I try to allow each child to respond in their own way. I do not stop the tears, or tell them we will get another kitten. But I do offer comfort. I do let them know that if we were not fostering and caring for the kittens, they would have died anyway. That they would have passed alone and uncared for. That we will try to find the strength to do it again-to help another homeless, cast-off kitty.
And I like a little "funeral" ceremony as we bury the animal. Say a few words, allow others to say a prayer.
I'm not ready for kittens yet, but by next spring, aka kitten season, I plan to be ready for another litter. You will slowly heal, too. And if God brings you another tiny life to care for, you will try again.
Rest in peace, tiny baby. I'm so glad for your sake that you had a good Meowmie and loving children to ease your passing over the Rainbow Bridge. The fighting and pain is over. Enjoy romping with the other kittens.
Rest in peace Odie, Mattie, B.B., Zero, and Kiss. You remain in our hearts, sweet babies.
