Sandie,

Ask your vet about Pemphigus Aereolis (sp?). All the symptoms you've describe are identical to PA, a suppressed immune system problem.

The cat's immune system kills the cells that make new skin. It causes painful scabs and itching. Advanced PA means it's spread to the nailbeds. My cat RB Marina Mar had it and by the time I caught it (the vet diagnosed her with ringworm) it was in the advanced stages.

You and Bobby will be in my thoughts and prayers.
