wild and domestic animal

Mithai's teacher asked ''Name some domestic animals'',

Mithai replied ''cow, tiger, cat''.

Teacher probably said her, no tiger is not domestic animal.

Mithai said ''magic man P C sarkar has a pet royal bengal tiger, my daddy told me and dogs too were wild, when man know how to tame dogs become domestic''

Mithai comes back home and said to me the above and also the fact that the Teacher asked her to follow what the book says and not to argue!
