I have two males, both 5 months of age. Today they got A LOT of out of cage time. When I put them back, Ashe (my super lovey, cuddly one.) went and curled in a corner. Is it because he's just tired? When I opened the doors he licked my hands but didn't make any motion to get out as usual. He is grooming himself normally but he just isn't as hoppy and lively.
