Everything You Need to Know About FIP Injections

Gather your supplies in a calm, quiet space. Let the vial reach room temperature for optimal comfort. Draw the prescribed dose slowly and tap out any air bubbles. Take a deep breath—you've got this, and your cat is counting on you.

Gently pinch the scruff of your cat's neck to create a skin tent. Insert the needle at a 45-degree angle into the subcutaneous space. Inject slowly and steadily. Most cats barely notice—the scruff area has fewer nerve endings. You're doing amazing.

Offer a small treat and gentle praise after each injection. Monitor the injection site for any redness or swelling (rare). Keep a simple log of dates, times, and any observations. Consistency is key—same time each day helps establish a routine.

Each order includes GS-441524 vials at 15mg/ml concentration, sterile 3cc syringes, appropriate gauge needles for subcutaneous injection, and our comprehensive FIP treatment guide with visual instructions.

Our team is available 24/7 for any questions or concerns. Reach out if you notice unusual reactions, need dosing guidance, want injection technique tips, or simply need encouragement. You're never alone in this journey.
