Who was innocent and guilty?

One night l asked my mom to tell me a story. She told me the story of her childhood. She had a pet-cat named Chimi. My mother's aunt was having a cat named Mani and Chimi was the baby of Mani.

My mom loved her very much, that time my mother was 13 years old. Chimi was very cute, her colour was snow white and two black patches around her eyes. Her eyes were blue in colour. When my mom used to come from school Chimi used to sit near the door. When mom entered, she used to meddle around mom's legs for milk. Mom told me one main thing about her.. that Chimi was totally vegetarian, she never tested rat though flesh is her food. Chimi was my mom's best friend. They both used to play like siblings. When mom was telling about Chimi her eyes became little wet... that shows how much she loves Chimi .

For Chimi my grandpa's tummy was her soft bed which used to move up and dow . She was younger daughter for my grandpa. Chimi was close to my mom's friends too. After few days one servant, who was working in grandpa's farm, he found one brown colored bunny. Bunny lost his mother, he was became lonely. So, mom decided to keep it with her.

Mom loved it like Chimi. Mom named it Shashi. Mom fed it milk with little spoon. After few days Shashi also became mom's part of life. As Chimi ,Shashi also played with mom. He used to sit near door and wait for mom. One day mom came from school as usual and she found that Shashi sat in a pool of blood. She was shocked! She cried and called her brother and cousins.. "Rajesh.. Seema.. Gopal come fast." There was Chimi sat beside Shashi with bloody nails. Mom took Shashi to the doctor. But unfortunately she couldn't save him.

Mom never became angry with Chimi. But there was one question which bug her yet. That is "Why, did Chimi tear, Shashi's tummy? " Although, she never tested rat or any other animal's flesh. Mom loved Chimi unconditionally. But there was little pain in mom's heart for Shashi. After getting married mom estranged from Chimi. When mom used to come at her mom's place, Chimi and mom play as usual.

When I was 6 months baby, Chimi died. When mom was telling me about her pets, her eyes were became wet, her sound became heavy,sometimes she cried also. That all proved me that how much they loved each other. There love was unconditional, pure and true.

Now, I come to know that why my mom don't allow me to bring any pet at home.

There is one question in my mind also like mom who was guilty and who was innocent? Chimi or Shashi?
