Good morning,

I am glad that Pepper is doing a little better this morning. You are correct, Prednisolone is a type of steroid (similar to Prednisone). If Pepper had asthma, the Prednisolone would have made a significant difference in his breathing, etc. From the sounds of his reaction to the Prednisolone and the continuation of the sneezing problems, it is likely he has allergies. I hope the vet will provide him something that helps.

P.S. FYI, in human medications there is a liquid form of Prednisone. For those cats that don't like taking pills this maybe another option...
