Not cool.Is it considered cruel to play mice 5 hours of hard rock music 5 days a week?
as long as it is not loud or hi-pitched they should not go deaf. other than that there is nothing i can think of as cruel.
it probably doesn't matter any more they r probably deaf from ur music.
Of course not. Now if you played country you could go to jail for a long time.
well if it isnt loud then its not that bad.
