Oh that's awful! I am so sorry.
We live fairly rural and a few weeks back I was out at around 6am and saw a coyote crossing the road about 1/2 mile from my house. Whenever I let our dog out (100-lb lab) I am still cautious because coyotes don't care about size.
I'm grateful I don't have to deal with the variety of predators you get in the US! Such a variation too, it would make it hard to protect from all of them. You proof it from the big ones then you get something like a weasel squeeze through the tiniest gap or a crafty raccoon figure the latch out!
