Smaller cats and cubs may be kept in the house with the right approach. Supervision is required to protect cats from things they might eat which would be harmful to them. Some train fairly easily while others are more difficult. Some prefer water, their native toilet, while others use a litterbox filled with conventional material. Just as with humans, any form of surgical procedure should be given a lot of thought.
Tooth removal is discouraged in all but the most extreme cases or for reasons of health.
Proper handling makes this safety concern totally unnecessary and it is actually more dangerous to remove the canines. Declawing is recommended for the larger species kept by those who are not professionals. But, again, it is an individual preference. The actual surgical procedure differs from that usually performed on the domestic cat, so your veterinarian should be consulted. Contrary to rumor, neutering does not tame a wild cat, nor does it in any way stop spraying.
