To use, simply open the can and serve the pate to your cat. You can serve it at room temperature for the best flavor. Store any unused portion in the fridge and use it within 24 hours. Always provide fresh water alongside the food. Keep the cans in a cool, dry place away from direct sunlight. If your cat has any known food allergies, check the ingredients list carefully. Also, it's a good idea to gradually introduce this new food to your cat's diet to avoid any digestive upset.
