I recently found a new vet, she gave my baby Revolution, topical antibiotics n told me to give her Chlorpheniramine. I'm nervous about giving it to her bc we still do not know what she is actually allergic to. The vet said she "thinks" it's a food allergy. But when this first happened I changed her food. My other cats also scratch, they don't have fleas, but cream is just worse. My boyfriend uses baby powder ALOT N I can't help but wonder if it's that... any thoughts or advise would be very helpful
