  • If wet or dry FIP cats develop ocular or neurological symptoms, their dosage should be adjusted accordingly.

  • To account for weight gain, adjust the GS dose on a weekly basis.

  • Many cats can gain a lot of weight, either because they were underweight to begin with or because their growth was disrupted by FIP. A cat's weight that doesn't increase or return to normal during treatment is considered a bad sign.

  • If the dose needs to be raised, add +2 to +5 mg/kg to the standard recommended dose for 4 weeks. Failure to see improvement after increasing the dosage suggests that the current level is still insufficient or that drug resistance is taking place.
