    HAIRBALLS: Cat Probiotics can help prevent cat hairballs from forming. As probiotics help improve cat digestion, it also helps to pass any undigested food attached to the hair sitting on the digestive tract easily before it even becomes a hairball. Common signs of hairballs in cats include: retching, gagging and a decreased appetite.
  • OVER-GROOMING: Excessive grooming often occurs as a result of allergies. Cats groom themselves to relieve itching. Strengthen your cat's immune system with this mix of Probiotic for cats to help reduce excessive grooming.
  • ALLERGIES + IMMUNE SYSTEM: A cats immune system is dependent on a healthy gut. A strong immune system is the first line of defence against cat allergies. Probiotics play an important role in promoting a healthy balance of intestinal flora in the small and large intestines. Cat allergy symptoms include: scratching, rubbing or shaking their head, wheezing, sneezing, coughing, gas, bloating, diarrhoea or vomiting.
  • DIGESTION: Adding probiotics to your cats regular diet helps them maintain good gut health and a stronger immune system. Did you know that 70% of a cat's immunity lies in its digestive tract? Healthy microflora (good gut bacteria) is essential for optimal gut health. Help your cat to fight diseases and achieve optimal gut health with our Probiotic for Cats.
  • ENCAPSULATION PROCESS We use micro-encapsulation to ensure the stability and viability of our probiotic strains, meaning it is able to survive acid in the stomach. The micro-encapsulation protects the bacteria from heat, moisture and light and is designed to become active in the small intestine. This makes our formula extremely potent.
