Question: In which cases, must we pay khums on animals kept at home?
Answer:
In general, if we keep them to use their products (such as eggs, milk,
wool) ourselves, they are not subject to khums (of course, if the
products themselves are not consumed by the end of the khums year, they
are liable to khums). However, if we keep the animals to eat their meat
ourselves or to raise, and sell, them, their khums must be paid every
year.
