From a Jain perspective, keeping a cat is not inherently against dharma, as long as you follow the principle of ahimsa (non-violence) in how you care for the animal.

Key points to consider:

• Non-violence first: Ensure you don’t cause harm, fear, or suffering to the cat or other beings in your care. This includes humane housing, regular veterinary care, and a peaceful environment.
• Feeding and care: If you feed the cat, try to minimize cruelty and harm. Many Jain households are vegetarian; some cat foods are meat-based, which involves animal slaughter. If possible, look for ethical options or seek guidance from a trusted Jain teacher about how to balance caring for a carnivorous pet with ahimsa.
• Impact on others: Consider whether having a cat might disrupt your ability to practice ahimsa in other areas (e.g., if the cat’s care leads to harm to birds or small animals in your surroundings, or if you personally struggle to maintain compassionate conduct).
• Intention and discipline: The intention should be to cultivate kindness and restraint. If you can maintain a calm, compassionate routine and avoid unnecessary harm, it aligns with Jain principles.

Bottom line: It can be okay to have a cat if your care is compassionate and non-harmful, and you are mindful of the ethical aspects involved. If you’re unsure about your particular situation, seek guidance from a Jain teacher or elder who can offer advice aligned with your tradition.
