Well, she brought a dead duck to the back door one day this winter (see the TMI thread for details). I have found dead squirrels in the backyard, but it's hard to know if she killed them. They were still in one piece. I made her drop a live duck once and I made her drop a baby rabbit once. The rabbit was no longer alive. I'm afraid to think about what she eats back there. Personally, I think she just wants to play with them and kills them by accident. She's never had blood on her. I don't think I could handle that. After the first duck incident (the live one), my daughter was really mad at her. My logic? She's an Alaskan Malamute. By instinct, she finds whatever food she can, whenever she can. In her "wild" state, she would be in the arctic and never know where her next meal was coming from. Therefore, she eats anything she can, whenever she can. It's not her fault.
I had a bird feeder near the side of my house, right next to a bush for a while. I started finding dead birds and figured it was West Nile, honestly. Then I came home from work one day and when I slammed my car door, the neighbor's cat, Bob, came out from under the bush that was right next to the bird feeder. I stopped feeding the birds. It was not intended to be bait for the birds so the cat could kill them! When Bob was mad at his family for getting a new kitten, he left me gifts of dead birds and mice on my porch. He was trying to get me to take him in, since they had "betrayed" him. That cat still loves me. They don't live next door anymore, but when I go to their house, Bob shows up from where ever he was hiding and jumps in my lap for me to pet him. I think he misses me

I miss him because I used to know the mice in the neighborhood would never be a problem as long as Bob was on the job!
