Purina Pro Plan Veterinary has introduced three new science-informed nutritional products to address common clinical needs in feline patients.
According to the company, the new therapeutic diet and liquid supplements provide veterinary teams with additional targeted options for specialized care:
- UR Urinary St/Ox + Calm Feline Formula: Available Nov. 23, this therapeutic diet is designed to manage stress-related urinary conditions. It is formulated to dissolve struvite stones and reduce the risk of struvite and calcium oxalate stone recurrence.
- Joint Care Supplement: Available now, this feline-friendly liquid formulation features omega-3 fatty acids to support joint mobility and L-leucine to help maintain healthy muscle mass.
- Hairball Care Supplement: Available now, this liquid supplement contains functional cellulose to minimize hairball formation and support normal bowel function. It is designed for cats that need targeted support while remaining on their current diet.
“Nutritional science has advanced tremendously, and today’s solutions must account for more than just cats’ clinical needs,” said Dr. Martha Cline, Purina veterinary nutritionist. “They also need to fit the realities of pet owners’ lives.” She added that Purina’s goal is to help veterinary teams make confident recommendations and to give cat owners practical solutions they can incorporate into everyday care.
