Who is it for?
This supplement is aimed at adult cats that show signs of stress or anxious behaviour during everyday disruptions — moving homes, new pets or people in the household, travel, or boarding. It's a reasonable option for owners who want a daily, food-based approach rather than a situational product.
It is not a replacement for veterinary care. If your cat has sudden behavioural changes, speak with your veterinarian first.
Feeding & use
Follow the dosing directions on the product packaging, typically one sachet per day mixed into your cat's regular food. Purina recommends giving the supplement daily for at least six weeks to see the intended behavioural support, and continuing daily use for ongoing benefit.
Introduce it alongside your cat's normal diet — no need to change foods. Store sachets in a cool, dry place.
