i had a similiar situation, although it was only with one animal. i know it's a tough decisoin to make! maybe you could sit your mom's husband down and explain your concern. also to your mom too. do they live on a farm, they'd have to to have that many animals! if you feel you cant report it yourself, maybe hint around to someone who would. sticky situations make for tough decisions! what i decided to do in my situation was give it a couple weeks, if they dont realize it by then, well, i'll have to do something.
