An indoor enclosure for a fennec fox should be spacious, secure, and enriched with hiding spots, climbing platforms, and soft bedding to mimic their natural environment and support their active, digging nature.
It should be at least 8 feet by 4 feet and height enough for climbing toys. This space lets them stay active even inside.
Fennec Foxes come from hot deserts, so they need shade in their enclosure to stay cool.
