RespiraCat L-Lysine for Cats – 250 mg Soft Chews for Immune & Respiratory Health

One Simple Chew a Day

You already do a lot to keep your cat healthy. RespiraCat is built to be the easy part.

Every soft chew delivers a defined 250 mg of L-Lysine, formulated to support your cat's immune system function, support respiratory health, and help maintain a normal immune response — as part of a consistent daily routine. No powders to measure. No pills to hide. Just a chicken liver–flavored chew your cat looks forward to, and a feeding routine you don't have to think twice about.

• Supports immune system function — a defined daily dose, not a guess.
• Supports respiratory health — 250 mg of L-Lysine in every chew.
• Helps maintain a normal immune response with consistent daily use.
• No measuring, no pills — a soft chew fits into feeding time, not around it.
• Weight-based feeding — one look at the chart tells you exactly how many chews, every day.
• Resealable jar keeps all 70 chews fresh and secure between servings.

250 mg. One Chew. One Routine.

When you're giving your cat something daily, you shouldn't have to wonder what's in it or whether you're giving enough. RespiraCat removes the guesswork: every chew has exactly 250 mg of L-Lysine, and feeding is based on your cat's weight, not a vague "as needed."

There are 70 soft chews in every resealable jar — enough for a full routine, clearly laid out from day one.

Why RespiraCat?

Everyday support for immune health

RespiraCat is a daily nutritional supplement formulated to support your cat's immune system function and help maintain a normal immune response — the kind of steady, background support that's easy to keep up.

Support for respiratory health

L-Lysine gives RespiraCat a clear job: straightforward nutritional support for respiratory health, built into a routine you already have.

No measuring. No guesswork.

Every chew has a defined 250 mg of L-Lysine. The feeding directions are based on body weight, so you always know exactly what you're giving.

A chew, not another pill

A supplement only helps if you can actually stick with it. RespiraCat's soft chew, in natural chicken liver flavor, is built to fit into feeding time rather than fight it.

Real size. Real color. No surprises.

What you see in our product photography is what you can expect to find in the jar. Each chew is approximately 20 mm × 10 mm × 10 mm, and our product images are designed to show the chews at a realistic size and appearance.
