Recently he got upgraded from a 3' enclosure with swing doors to a t10 with sliding doors as a temporary till his big enclosure comes. He was not happy with the upgrade and was cramming his face between the door and litter dam. His face started to get swollen. The main difference in the enclosures was the 3' had a 3" vent. The t10 got more ventilation installed. Since then he has stopped trying to get out and his face swelling has gone down. Still no issues with being combative.
