God bless everyone for the compassionate replies. We buried sweet Clovie on Saturday and I read some prayers from a book I have called "Gods Creatures Great and Small." And of course, I wept. But I know my dear special little girl will always live on in my heart. Shamrock seems to be taking the loss of his "sissie" okay - he's kind of a mellow guy so it's hard to tell exactly what he's thinking. But I spend extra time with him to make sure he doesn't feel lonely.
If all goes well, he should be getting another companion soon. I'm just not the type that can have just one bunny - I have to have two, it just feels right. For one thing, I just never want to be bunnyless. You can imagine I'm keeping a close eye on Shammie and he is absolutely forbidden to get sick! Well, he always is, anyway but he gets constant reminders of that right now. I'm being a "helicopter mom."
Plus we have a rescue club in my town that I got involved with a couple years ago, and now the founder is going to have to retire from it in a few months. I and some of my fellow members hope someone will be able to keep it going, but that's uncertain. So if I give a home to one of the bunnies that will help. It's a win-win.
