I saw the pictures of Furball in another thread and he was certainly a handsome fellow and well-loved by you and your husband. When you are very young and first married and have this little life to care for together, it creates a little family that you can never forget. Furball was your first "child," ya know? If people don't understand that, then ignore them. Besides, you know where to come to get the support you need
We all know exactly how you feel...or at least we've been there. I lost 4 babies in 3 years and to this day I cannot look at pictures or even think of them for more than a passing glance at a memory without crying. Dang...see? I'm crying even now
In fact...about 11 years ago, while I was pregnant with my daughter, I decided to crochet a blanket for my mother to keep myself busy. My handsom Sampson kitty loved to "help" by unravelling yarn and sleeping in the warmth of the half-made blanket on my lap. Sampson's life was cut tragically short when he was just 3 years old, though, when he was hit by a car while I was visiting a friend in Utah. I was devastated. Last weekend my mom asked me over to help her clean her house in preparation for my brother's return from 2 years in Poland (he's a consular in the Embassy there) and I found that blanket in her closet. Didn't think of Sambo at first, but then I saw it - a jet black cat hair, woven right into the yarn. It hit me and I positively SOBBED...11 years later.
So cry as much as you need to, mourn him and never forget him, just don't let it consume you and you'll be fine.
