It's ok, Heff. You knew the time was coming and were somewhat prepared, as much as you can be prepared to lose someone. It was the same for me when we put Eli to sleep. I prayed and prayed for him to go in the nite, he only had arthritis, but I prayed for him to die in his sleep, comfortably, so I wouldn't have to do the deed. I cried sooooo hard when we took him there to put him down. I cried for like 20 min afterward, and then it was like I was all cried out. I just stopped crying. Then we left and I layed on the couch, watching tv and not thinking about it, and petted my stuffed rottie, Peaches, like he was Eli sitting in my lap. I didn't cry about it again until that nite. I stayed up 1/2 the nite crying, and I think I did the same thing the next nite. Then it was like I had nothing more to cry about, so I stopped. Haven't cried since. Have gotten misty eyed, but not cried since then. We only had Eli for 9 months. Immediately when we got home from the vets office that day, I wanted another dobie. Just to fill that empty space that a big dog leaves when he is gone. I still want one so badly, but it doesn't look like that's gonna happen. People just grieve in different ways, Heff. Don't feel bad about it. She knew she was loved and that you miss her. It's ok to have another cat already. Allie isn't her replacement, she's just filling the space Miss Kitty left for you.

Everyone reacts to death differently, and everyone has a different grieving period.  i think it also just depends on the cirumstances.  when jerry my gerbil died i cried for days, but yet when my bird moe died (we knew she was old and sick) i cried a lot that night, but that was it.  so i think it just depends!
