My cat's now 6 years old & since Christmas has been excessively grooming. Our vet never checked if it was medical or not. She's being treated for Psychogenic alopecia but isn't getting better, nothing has changed other than her being less hyper. I've believed from the start that she might have dandruff or a skin irritation. Have no idea what to do. Mom would be upset on having to take her back to the vet.
