TL;DR: Purina Pro Plan Calming Care is a daily probiotic supplement for adult cats, using the BL999 strain to help cats maintain calm behaviour during external stressors. It's made for cat owners who want a food-based behavioural support option developed with veterinarians and Purina researchers.
Calming Care belongs to Purina's Pro Plan Veterinary Supplements line, formulated with input from Purina pet nutrition experts, researchers, and veterinarians. The formula centres on one specific probiotic strain, BL999, selected for its role in supporting calm behaviour in cats.
If your cat gets unsettled during routine changes, vet visits, or household disruptions, purina feline calming care is one of the more widely recognized probiotic options in this category.
What does Purina Calming Care do?
The BL999 probiotic strain is included to help cats maintain calm behaviour and to promote positive behaviours such as playing and seeking out social contact. It is intended to support cats through external stressors — changes in routine, travel, or a new environment.
It is a daily supplement rather than a situational product, so it works alongside your cat's normal diet instead of replacing any part of it.

Who is it for?
Purina calming care for cats 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 suits owners who prefer a daily, food-based approach rather than a one-off calming product.
It is not a replacement for veterinary care. If your cat shows sudden behavioural changes, speak with your veterinarian first.
How do you give Calming Care to a cat?
Follow the dosing directions on the product packaging — typically one sachet per day mixed into your cat's regular food. Purina recommends daily use for at least six weeks to see the intended behavioural support, with continued daily use for ongoing benefit.
No diet change is required; simply stir the powder into the food your cat already eats. Store sachets in a cool, dry place.
Feeding & use
One sachet daily, mixed into wet or dry food, is the standard routine for purina calming care cat households. Many owners serve it with the morning meal so the daily schedule stays consistent.
