- VET-GRADE IMMUNE SUPPORT FOR CATS: Doctor By FELYSIN features a potent three-way synergistic formula with L-lysine for cats, mushroom-derived beta-glucan, and taurine—a combination unmatched by other cat immune support supplements. It supports a healthy immune response in cats experiencing sneezing, runny noses, and watery eyes caused by seasonal or environmental stress. With its delicious, lickable cat supplement format, your cat can enjoy it as a daily reward.
- RESPIRATORY & EYE HEALTH DEFENSE: Specially developed for cats prone to upper respiratory issues and eye health concerns, as well as those needing seasonal allergy relief. While L-lysine supports healthy respiratory function in cats, beta-glucan strengthens the body’s natural defense system. Trusted by cat owners managing feline herpes, nasal congestion, and recurring discharge in their cats, our formula promotes fast recovery and daily comfort.
- 97% PALATABILITY – NO-MESS LICKABLE TREAT: Stop struggling with powders, tablets, or sticky gels that cats reject. FELYSIN uses a “Churu-style” lickable cat supplement format that cats instinctively love. Simply squeeze and feed directly, mix it with food, or add it to water. Our individually packaged sticks mean no mess and zero waste—no more “supplement wars” with your picky eater.
- 100% HUMAN-GRADE INGREDIENTS & CERTIFIED SAFETY: We use only premium, human-grade cat supplement ingredients: real chicken, L-lysine, taurine, and shiitake mushroom mycelium powder. Our products are manufactured in HACCP- and ISO-certified facilities, with quality checks conducted every 3 months. With no artificial additives or fillers, the formula is safe for daily use by kittens and senior cats, with no side effects or gastrointestinal issues.
- 30 INDIVIDUAL TUBES FOR PRECISE DOSING: Each tube provides a precise dose of your cat’s daily requirement, eliminating the need for messy scoops or guesswork. This 30-count pack is perfect for multi-cat households and is travel-friendly, allowing for consistent care on the go.
