Tasty, artificial chicken-flavoured capsules your cat will love
Capsules can either be given whole or sprinkled onto food, to make supplementing your cat’s diet easy. Simply follow the on-pack guidance to find the dose and schedule that’s right for your pet.
 

Supports a healthy bladder lining
Normal, healthy bladders are lined with glycosaminoglycan (GAG), protecting it from direct exposure to urine, which can activate nerve fibres that make your cat feel uncomfortable. The N-acetyl D-glucosamine and hyaluronic acid in Protexin Veterinary Cystophan Daily Supplement Capsules for Cats provide essential building blocks that help maintain this protective layer.

  • "Works perfectly with prescription foods for urinary issues "
    Posted byMeganon16th Apr 2026

    My cat had 2 surgeries for urinary blockages. 1st surgery I used this and he healed up within a week. After his second surgery for more crystal blockages (took us a while to adjust to this issue) I stopped using it worried it wasn’t helping. 10 days go by and he’s still struggling with painful urination and not getting better. Another expensive trip to vets with no real answers so I put him back on these (along with his royal canon s/o urinary food) and I saw improvement within hours!!! Within 2 days he was back to normal. While the food breaks down the crystals, this stuff works like ural sachets do for us lol takes away the sting but these also help with well-being which is just as important as the medicine.
