If Bugs responded to steroids and antihistamines it may be an allergic reaction. You may talk to your vet about allergies caused by flea bites, food allergies, or environmental allergies. In some pets, 1 flea bite can cause a body-wide allergic reaction. He may also need a hypoallergenic cat food for a few months. Common causes of increased eosinophils are allergies, parasites (external and intestinal parasites), and fungal infection.
