Early social gaps quietly reshape adult feline behavior.

A single kitten raised without siblings rarely looks different at first. Food arrives on time. Hands replace littermates. The environment feels calm, controlled, even ideal. Yet researchers have long flagged these situations as quietly consequential. Social learning normally unfolds through constant friction. When that friction disappears, development does not stop. It simply redirects. The effects stay hidden for months or years. Adult behavior becomes the first real signal, surfacing differences that feel emotional, puzzling, and difficult to trace back to those earliest weeks.
