Oh, I'm so sorry, Boomerang. i understand the need to have another pet in a fairly short time. I think that for some people that feels disloyal and for others it just doesn't.
I know there's no way I could miss my pets who die any less, just no way. I miss them with this huge, aching, sense of loss that can't be diminished by a new face in the household.
The last time I lost a pet (a cat I'd known since I was five) was about five and a half years ago, and I to this day I still cry over her sometimes [size=8](I miss you Stubby)[/size]-- my cat who was a kitten at the time was a comfort, but never a replacement.
I think the next time I lose one of my gang, I'll have to find a new friend of the furry variety very soon afterwards-- just because it does hurt
so much, you need to feel like life is not quite so desolate, and a house just doesn't feel right without a little crowd of animals
. Do what you need to do, you'll mourn no matter what.
