In the short story, Boys and Girls, describe the foxes pens.

From the text:

Alive, the foxes inhabited a world my father made for them. It was surrounded by a high guard fence, like a medieval town, with a gate that was padlocked at night. Along the streets of this town were ranged large, sturdy pens. Each of them had a real door that a man could go through, a wooden ramp along the wire, for the foxes to run up and down on, and a kennel — sometimes like a clothes chest with airholes — where they slept and stayed in winter and had their young. There were feeding and watering dishes attached to the wire in such a way that they could be emptied and cleaned from the outside. The dishes were made of old tin cans, and the ramps and kennels of odds and ends of old lumber. Everything was tidy and ingenious; my father was tirelessly inventive and his favourite book in the world was Robinson Crusoe. He had fitted a tin drum on a wheelbarrow, for bringing water down to the pens.

Do the foxes enjoy living their cages? What in the extract above allows us to understand what the fox fells?

No, the foxes did not enjoy living in the cage. Though they were well fed and were kept in a tiy environment ultimately narrator's father was going to kill them and peel off their skin to sell it when the time comes. Foxes are wild animals and will never be happy in a cage.
