Welsdom Cat Immune Chews — 60 Chews

Cat Immune Support Chews — Formulated to Help Your Cat Stay Strong

Most cats receive little targeted immune support from their everyday diet. When stress, seasonal changes, environmental allergens, or simply the demands of aging place pressure on your cat's immune system, the right nutritional support can make a measurable difference. Tail & Tonic's Welsdom Cat Immune Chews are formulated with a concentrated blend of clinically-studied botanicals and amino acids designed to reinforce your cat's natural immune defenses from the inside out.

What Makes These Chews Different

Unlike broad-spectrum multivitamins, these chews target immune function specifically. Each chewable tablet delivers four key actives in meaningful doses — not token amounts. The formula is veterinary-inspired and manufactured in Canada to GMP standards.

Active Ingredients Per Chew

• L-Lysine (200mg) — An essential amino acid that supports immune cell function. L-Lysine is one of the most well-researched supplements for feline immune health, particularly for cats who carry feline herpesvirus (FHV-1). It does not produce an adverse reaction in cats and is widely recommended by veterinarians for routine immune maintenance.
• Saccharomyces cerevisiae / Nutritional Yeast (78mg) — A natural source of beta-glucans and B vitamins. Beta-glucans are polysaccharides that prime immune cells (macrophages, natural killer cells) to respond more efficiently to pathogens. Nutritional yeast also provides nucleotides that support rapid immune cell proliferation.
• Astragalus membranaceus (38mg) — An adaptogenic herb with a well-documented role in traditional veterinary medicine. Astragalus helps modulate immune response, supports T-cell activity, and has demonstrated antiviral properties in multiple peer-reviewed studies. It is considered safe for long-term use in felines.
• Quercetin-3-rutinoside (26mg) — A bioflavonoid antioxidant derived from rutin. Quercetin helps reduce oxidative stress that can suppress immune function, and has anti-inflammatory and anti-allergy properties. It works synergistically with Vitamin C to improve cellular antioxidant capacity.

Who These Chews Are For

These chews are suitable for cats of all ages and are particularly beneficial for:

• Senior cats (7+ years) whose immune function naturally declines with age
• Cats that have experienced recurring upper respiratory infections
• Indoor/outdoor cats with higher pathogen exposure
• Cats recovering from illness, surgery, or stress
• Multi-cat households where infection spreads easily

How to Use

Serve 1–2 chews daily, given directly or crumbled over food. The chews are palatable and accepted well by most cats. Begin with one chew daily for the first week before introducing a second if recommended for your cat's size. Results are typically noticeable within 4–6 weeks of consistent daily use.
