Kitten in a Box

We caught this kitten on our deck, a feral mom had a litter in the woods and was coming with them onto the deck for food. We caught one kitten earlier, and took it to the shelter, after one week of taming. Later we caught this guy, for the longest time he seemed hopeless as he was so wild. We have kept him and neutered him, and he is growing up safely indoors. We live on a farm, haven't seen his momma since.
