VetriScience Vetri Lysine Plus Soft Chews
VetriScience Vetri Lysine Plus Soft Chews earn a spot for offering a highly palatable soft-chew format that many cats accept readily, providing complementary digestive and immune support for owners seeking an easy daily treat. While not primarily a probiotic product like others on this list, its lysine-focused formulation can reduce stress-related digestive upsets and pairs well with targeted probiotics (such as Purina or Zesty Paws) for multi-modal care; financially it is often priced competitively for owners who want a palatable maintenance chew rather than a concentrated probiotic dose.
