I don't know which is worse..a spider or a vole. My siamese very proudly, one early morning, killed a vole. Wanting to share her catch with me, she came on the bed while I was sleeping and dropped the vole on my chest. I was just waking up and thought the vole was one of her paws and started petting it until the light bulb turned on in my brain that the cat was sitting at the bottom of my bed, waiting maybe for praise. Later that day my neighbor asked me what was all the laughing at that early hour coming from my house...but it was not laughing...it was my screaming....
Waking up with a dead vole on your chest is definitely worse!
I just thought it was odd that my cat brought an insect to me. Though, I guess that is all the "game" he has access to.
