I love this thread! Toto is also a "killer"! It's the funniest thing I have ever seen ... she chases and shakes a toy, beats it on the floor and holds it up in the air shaking it so hard, sometimes I worry she will hurt her neck!!
The funniest thing is when she is shaking it so hard she loses her grip on it and it flies up in the air ... she just looks so puzzled, standing there looking like, "where did it go?"!
I find toys in the oddest places ... table, kitchen counter, etc. I really watch her if she happens to be killing something in the kitchen ... don't want a gorilla cooked in our food!!
BTW ... she only "kills" her stuff and isn't agressive to humans or other animals.
