Most Cat Supplements Leave You Guessing

Bright pouches, vague scoop sizes and a photo of somebody else’s cat. Read the one-star reviews and the same complaints keep coming up. Among them: the product looked nothing like the picture, and nobody answered when buyers asked for help.


RespiraCat is built around those complaints. You get a defined dose, feeding by your cat’s weight, chews shown at true size and true color, and a real person behind the email address.


A simple daily routine

250 mg of L-Lysine, in One Simple Daily Routine

Every RespiraCat 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.

  • 250 mg per chew: the same dose every day, with nothing to measure

  • Formulated to support immune system function: simple daily support you can build a routine around

  • Soft chew: no powder to scoop and no tablet to split

  • Feeding by weight: up to 5 lb, one chew per day; over 5 lb, two chews per day

  • Natural chicken liver flavor: in a resealable jar that keeps all 70 chews fresh

True size, True Color

We show the chews at their real size and real color, so you know what is in the jar before it arrives.

Comes in a Jar, Not a Pouch

A resealable jar holds all 70 chews and closes tightly after every serving.

A Real Person Answers

Getting Started Takes Three Simple Steps

  1. Check the cat's weight. Up to 5 lb (2.25 kg): 1 chew daily. Over 5 lb (2.25 kg): 2 chews daily. You can give one in the morning and one in the evening.

  2. Offer the chew. Give it on its own or with your cat’s food.

  3. Keep it daily. It takes about 30 days of consistent use to judge any supplement fairly.


Consistency matters: the 30-day guidance is about building a habit, not a promise of results within 30 days.
