Protexin Veterinary Cystophan Capsules are formulated to provide high-level support for feline urinary health and help maintain normal stress levels. The advanced formula helps maintain the protective glycosaminoglycan (GAG) layer lining the bladder, which plays a vital role in shielding the bladder wall from urine irritation. It also contains L-tryptophan, which is used to makethe ‘happy hormone’ serotonin and maintain normal stress levels. With a palatable chicken flavour, Cystophan is a unique combination that reduces the number of products your cat needs to take.
