animal rights

my son told me the other day - I can't beleive you bought this - and showed me case for the cell phone, on which he read - lamb skin.
- Lamb skin! - he said, and looked at me with sorrow.
- What about kotleta? - I reacted right away. - Kotleta is a dead cow, you know.
- Don't talk like this about kotletas! - exclaimed my child tragically, - it's the best thing on earth, so tender, so good.
Guess, there will be no vegetarians in my family.
