Increasingly Vocal Chinchilla
I got my chinchilla (3 years old) in April. His previous owner was a chinchilla breeder, and told me I should expect some guinea-pig like vocalizations. However, he never made a peep! I heard him do a repetitive chirp once in July, and that was it until the month of September. Now, I hear him "talk" once or twice a week.
Is there a reason for this? He doesn't do it when he's agitated, nor does he seem pained or unhappy when he chirps. But I can't wrap my head around this sudden change. His main cage is in my room, and I supervise his outside play, so it's not as if I'm just around him more now.
