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

-Adjust GS doses monthly for weight growth.

Weight gain can be tremendous in many cats, either because they are so wasted at the start or that their growth has been stunted. Failure to gain a good amount of weight during treatment is considered a bad sign. 

If there are good reasons to increase the dosage, it should always be from +2 to +5 mg/kg daily and for a minimum of 4 weeks. If 4 weeks extends the 12-week treatment time, the treatment time is extended to accommodate. One should expect a positive response to any increase in the dosage and a failure to see improvement indicates that the dosage is still not high enough, drug resistance is occurring.
