There are laws prohibiting cruelty to animals both in Jewish and secular law. Do they extend to bugs? I know there is a court case concerning whether monkeys who retired from show business can be caged or do they have to be set free.
Is hunting for sport permitted according to Jewish Law? I think it’s prohibited. According to Jewish Law you can’t chop down a fruit tree just because you want too so surely a living creature can’t be killed just because you want too.
