Hi and thank you for posting your question on Petco Pet Education Center, formerly Petcoach! Sight unseen, it is hard to say exactly what the cause of the spots are, but I can certainly offer a few possibilities. Red sores and spots can have many causes. Food allergies being one of them! It is possible she was allergic to the food she was eating. If you switched foods and she is now better with no sores or spots any longer, then perhaps a food allergy was the cause. However, there are other causes such as a flea allergy, other environmental allergy, fungal infection (ringworm), bacterial infection. The feline herpes virus causes on and off upper respiratory symptoms like sneezing, coughing, and ocular infections. Sores are not typically caused by the feline herpes virus. If the sores are not getting any better or appear to be getting worse, you may want to take your cat into a veterinarian so she can be properly diagnosed. If the sores looks very red and infected, your vet may prescribe an antibiotic. I hope this has helped and I wish you and your cat the very best!
