Neutering a Cat
Q: Is a Noahide allowed to have her pet cat operated on to be neutered?
Q: Is a Noahide allowed to have her pet cat operated on to be neutered? The woman has read that Jews are not allowed to castrate a pet. Her cat has given birth twice and this is causing her problems.
A: Most rabbis feel that Noahides have not been given a command about castration, while a minority feels that this is forbidden. Some of the latter group, who forbid castration, feel that it applies only to human beings and not to animals, and some of this group feel that it applies only to a male animal and not a female. And among those who forbid castration of a female animal some only forbid a manual operation and not by using an injection or drugs.
My conclusion is that in view of the large number of those who permit neutering, the woman is allowed to have her cat neutered.
