In fact, some others have seemed to ignore tzar baalei chaim; why aren’t you pestering them?
Nobody is ignoring tzaar baalei chaim, just putting it into perspective. If you would check the sources (I’ll provide if you’d like) you would see that tzaar baalei chaim is muttar for human benefit.
Rabbi Moshe Feinstein forbade production of milk-fed veal calves because of tzar baalei chaim concerns.
Interesting. Can you source that please?
