The property responded to the owner's residential building to raise 5 pigs! Is this behavior of the owner legal?

During the period, the owner of a residential area reported that there were owners raising pigs at home and five pigs in a building. Now, after investigation, the property also responded to this matter, saying that all five pigs were pet pigs, because the owner entrusted a friend to decorate the house and the friend put the pet pigs here. This behavior of the owner is still legal, because it is a pet pig and can be kept. If it is an ordinary pig, it can't be raised in the community. Raising pigs in the community stinks, and many residents can't stand it, so they report this behavior to the property. Now the property has been investigated clearly. These pigs are not ordinary pigs, nor carnivorous pigs, but pet pigs. These pigs are not big, and they are not as exaggerated as others have described. Because the owner entrusted the house to a friend for decoration, the friend temporarily put the pigs in his house, and now these pigs have been taken away. If the owner raises ordinary pigs, then this behavior is illegal and there are relevant regulations. Ordinary pigs can't be kept in residential areas, but the owner is a pet pig, and it can still be kept, because pet pigs are not big, so long as they maintain good environmental hygiene and don't affect others, it is no problem to keep pet pigs at home, but if they are ordinary pigs, they are not allowed according to relevant regulations. This behavior of the owner is still legal, because the owner keeps a pet pig and it hasn't been kept for a long time, so there is no problem. If the owner keeps ordinary pigs, this is not allowed. According to the relevant regulations, ordinary pigs cannot be raised in residential areas, which does not meet the regulations.
