This is so sad, my condolences to your friend.
One time, I found a piece of steak in our backyard. I ask my husband if he put it there and he said no, I thought you did!
(First of all, why the hell would I throw a piece of steak in the backyard?
Believe you me, I was pissed at him)
I put gloves on and immediately threw it out! I think our backyard neighbors tried to poison my doggies too! We have 6ft concrete walls and just because their stupid cat keeps teasing my doggies by sitting and staring at them, my doggies would bark at the cat. That does not give them rights to do that to my doggies!!!
The cat even has the nerves to go in my backyard sometimes and my doggies would run there and the cat would jump back to its yard. I swear one day Naboo will catch that cat!!!
