Pet supplements / best for urinary

Best urinary supplements, ranked.

Cranberry, glucosamine, and D-mannose urinary blends for cats, where the controlled evidence is weak to negative.

Ranked by PetScored composite (evidence quality 30%, active dose 25%, ingredient clarity 15%, safety and manufacturing 15%, value 15%). This ranking is our opinion under a published rubric, not veterinary advice. A product can rank below a peer because its headline active is weakly evidenced or its dose is hidden, even when it is well made.

  1. VetriScience UT Strength Feline

    A fully disclosed, NASC-sealed cat urinary chew with a restrained support claim; the problem is the evidence, not the execution. A placebo-controlled trial of oral glucosamine for feline idiopathic cystitis found no benefit, and the 2025 feline consensus says glycosaminoglycans have no significant benefit, so a cranberry-and-glucosamine urinary supplement scores low on evidence no matter how cleanly it is made.

  2. NaturVet Cranberry Relief Plus Echinacea for Cats

    A cleanly disclosed, NASC cat urinary chew built on cranberry; the support claim is restrained, but cranberry has no controlled efficacy evidence in cats and most feline lower-urinary disease is sterile, so the anti-adhesion rationale does not even apply. Well made, weakly evidenced.
