An Unpleasant Incident

Two days ago we found a cat has delivered her two new born kittens on the cement floor in our building. The day was very cold and a friend of mine made a card-board box for them to secure. Today I saw the worst and unpleasant thing in my life. My own eyes couldn't believe This ferocious mother cat was breast feeding one and the other was half eaten, only two legs and the small tail remained Oh! what a catastrophe is this? I thought a blind is fortunate than me. Luckily my poor mother who was gone earlier without seeing such a heartbreak. The buddha must have seen a similar incident. That's why he was frustrated and left everything for a perfect bliss?
