Is OcuLabs L-Lysine Right for Your Cat?
Find the routine that fits your cat:
My Cat Seems Healthy

A familiar routine is a good place to add daily nutritional support.
OcuLabs L-Lysine is made for daily immune and respiratory wellness. Keep a complete diet, fresh water and regular vet care in place.
My Cat Is Getting Older
+
Older cats deserve a little extra daily care and close attention to changes in their habits.
Ask your vet how daily immune support fits with their age, diet and any existing care plan.
My Cat Gets Sneezy
+
Start with one capsule a day.
Every capsule helps maintain seasonal respiratory comfort. Ongoing sneezing, eye discharge or breathing changes need a vet's assessment first.

Check with your vet before starting if your cat is a kitten, has a health condition or takes medication.
I Already Use Other Supplements
+
More is not always better. The ingredients and your cat's needs matter.
Show your vet the full ingredient lists of the products you already use, so nutrients do not overlap.
