Summary:

  • Most FIP cats show clear signs of improvement within the first 3–7 days of GS treatment.

  • Appetite, energy levels, and fever often normalize first.

  • Mild setbacks like fatigue, digestive changes, or skin irritation from injections may occur.

  • Early monitoring of weight, temperature, and behavior is essential.

  • Owners should track daily progress to assess responsiveness and detect complications early.


What to Expect During Your Cat’s First Week on GS-441524 Treatment

When your cat is diagnosed with Feline Infectious Peritonitis (FIP), quick action is crucial. Consult your veterinarian immediately to confirm the diagnosis and start treatment.


GS-441524, provided by CureFIP, is the most effective antiviral medication available for FIP. It has helped thousands of cats recover, but the first week is especially critical. Knowing what to expect helps you feel confident, committed, and prepared for the recovery journey.


This guide is based on veterinary experience, real-life case reports, and feedback from thousands of cat owners worldwide. Below is a science-based timeline of what typically happens during the first seven days.


Day 0: Preparing for the First Dose


Before giving GS-441524, confirm the dosage based on your cat’s:


  • Weight (in kg)

  • Type of FIP (wet, dry, neurological, or ocular)

  • Administration method (oral or injection)


Recommended starting doses:


  • Wet FIP: 6 mg/kg

  • Dry FIP: 8 mg/kg

  • Neurological or ocular FIP: 10 mg/kg


If your cat shows little to no progress—or symptoms worsen—dosage adjustments may be needed. Always consult with your treatment provider.


✅ Prepare a quiet, stress-free space.

✅ Have syringes and separate needles (one for drawing, one for injecting) or capsules/tablets (for oral treatment).

✅ Keep alcohol pads, gloves, and a daily journal on hand.⚠️ Never inject your cat with the same needle used to draw medication.


Days 1–2: Subtle but Vital Changes


Within the first 24–48 hours, many cats begin showing small but important improvements:


  • Fever begins to drop

  • Appetite slowly returns

  • Slight increase in energy

  • Cats may seek food, attention, or affection again


👉 If your cat isn’t eating or showing progress by day 2, don’t panic. Some cases—especially neurological or ocular FIP—take longer to respond. Continue supportive care such as:


  • Appetite stimulants

  • Proper hydration (oral, subcutaneous, or IV as guided by your vet)

  • Comfort and rest


Days 3–4: Stronger Appetite and Renewed Energy


For many cats, day 3 marks a turning point. Owners often notice:


  • Significant boost in appetite

  • More mobility and playfulness

  • Improved grooming habits

  • Greater sociability and responsiveness


In wet FIP, fluid buildup in the abdomen or chest may begin to decrease. Cats that previously hid away may start roaming the house again.


👉 Tip: Keep daily notes on:


  • Food and water intake

  • Litter box usage

  • Weight changes

  • Behavior and activity level

  • Medication dose given


This record is valuable for both you and your veterinarian in tracking progress.


Days 5–6: Visible Recovery, Minor Side Effects


By midweek, most cats show consistent recovery in multiple areas. But some mild side effects may appear:


  • Injection site irritation (redness, swelling, tenderness) → Rotate injection sites daily and apply a warm compress to ease discomfort.

  • Digestive upset such as diarrhea or mild nausea (more common with oral GS).

  • Fatigue or mild muscle soreness.


These effects are usually short-lived and manageable.


⚠️ Seek immediate veterinary help if your cat develops:


  • Seizures

  • Sudden jaundice (yellow gums, eyes, or skin)

  • Persistent vomiting or worsening symptoms


This may signal underdosing or another complication. Your vet may recommend increasing the dosage based on the higher of your cat’s current or highest recorded weight.


Day 7: Reassess and Plan Ahead


At the end of the first week:


  • Re-weigh your cat and adjust the dosage if needed.

  • Recheck temperature, appetite, and energy levels.

  • Share updates with your treatment support team or vet.


If no improvements are seen:


  • Double-check GS dosage and product quality.

  • Consider possible misdiagnosis or other illnesses (like FeLV or toxoplasmosis).

  • Ask your vet about additional supportive medications (anti-nausea, steroids, appetite stimulants).


Most cats, however, continue to improve steadily in the weeks ahead.


Oral vs. Injection: What to Watch in Week One


Injection GS-441524


  • Works faster, especially in severe or neurological cases

  • Requires proper injection technique

  • Monitor for: ulcers, pain, skin abscesses


Oral GS-441524


  • Easier to give, especially for long-term use

  • Best for cats that eat well and tolerate oral meds

  • Monitor for: vomiting, inconsistent absorption if not given properly👉 Oral GS can be given directly or with a small portion of wet food.


Final Thoughts: Stay Committed, Stay Observant


The first week of GS-441524 treatment is a critical window that often reveals your cat’s ability to recover. Not all cats bounce back overnight, but many begin their healing journey here.


Stay patient, track daily progress, and remain consistent with supportive care. FIP recovery is a marathon, not a sprint—but with proper treatment, thousands of cats have regained full health.


And remember: you’re not alone. You can always reach out for help and guidance along the way.



FAQs: FIP Treatment and GS-441524


Q: Is it normal if my cat doesn’t improve in the first few days?

A: Yes. Some cats—especially with dry, ocular, or neurological FIP—may take 5–14 days to respond.


Q: Should I switch from injection to oral GS in week one?

A: Not unless instructed by your vet. Injections are generally recommended during the first 1–4 weeks, especially for severe cases.


Q: How do I know GS is working?

A: Look for steady improvements: better appetite, weight gain, higher energy, reduced fever, and less hiding.


Q: What if I miss a dose?

A: Give it as soon as possible, then continue the 24-hour cycle. Do not double up on doses.

  • Most FIP cats begin improving within 3–7 days of GS-441524 treatment.

  • Appetite, energy, and fever are the first signs to normalize.

  • Daily monitoring is essential for detecting early issues.

  • Minor side effects are common but usually manageable.
