Single cats without feline companionship have all their social and environmental enrichment needs met by human interaction and home environment design, requiring proactive management to prevent boredom and loneliness.
Single-cat welfare depends entirely on owner engagement and environmental design because the cat has no feline social partner to supplement human interaction. Owners working full-time who leave single cats alone for 8-10 hours provide inadequate social stimulation regardless of what happens when they are home. The welfare solution is either providing a second compatible cat or implementing robust automated enrichment programs that reduce the daily alone time experience. The assumption that cats are independent and do not need company during owner absence is contradicted by evidence that single cats in active households show better welfare indicators than cats in quiet single-occupant homes.
