A: It could be, but there are lots of other potential causes. Symmetrical hair loss under the abdomen can also be a behavioral issue called psychogenic alopecia. It’s a nervous habit much like nail biting in people. Your veterinarian can differentiate between psychogenic alopecia and medical problems that can affect your cat’s skin, including allergies to environmental stimuli or proteins in her food. Other potential causes include bacterial or fungal skin infections, hormone imbalances, and parasites. All of these conditions can be treated if diagnosed properly. Please make an appointment with your veterinarian to discuss your cat’s particular condition.
