Buying Guide

Identify the primary need

Choose formulas targeted to your cat’s issue—immune, skin & coat, liver support, blood sugar or high-calorie supplementation—rather than one-size-fits-all claims

Check active ingredients

Look for clinically relevant nutrients such as omega-3s, lysine, milk thistle (silymarin), vitamins and whole-food extracts tied to the stated benefit

Consider formulation and administration

Select chewables, powders, gels or tablets based on your cat’s preferences and ease of dosing to improve adherence

Assess source and processing

Prefer products with whole-food or minimally processed ingredient lists for complex nutrient profiles and digestibility

Match dose to cat size and condition

Verify recommended daily serving and whether the product is suitable for kittens, adults or cats with specific conditions; consult your vet for therapeutic needs
