Urgent Advice for Managing Your Cat’s Rodent Ulcers

In an urgent call for help regarding a 15-year-old cat named Sonny, pet owners are seeking expert advice on how to manage his rodent ulcers. This query was raised in the latest edition of the “Ask Dr. Paola” series on September 7, 2026, where Dr. Paola Cuevas (MVZ) shares her insights on feline health issues.

This weekly series is designed for cat lovers, whether you’re a novice or a seasoned pet parent, providing essential knowledge about your cat’s health and well-being. Dr. Paola addresses various topics, including nutrition, preventive care, and common behavioral issues, equipping pet owners to keep their feline companions healthy and content.

Dr. Paola expressed relief that Sonny is still maintaining his appetite, emphasizing, however, that changes in his behavior are concerning. Known scientifically as indolent or eosinophilic ulcers, rodent ulcers are a component of the feline eosinophilic granuloma complex and are often linked to hypersensitivity reactions. Although they may not be significantly painful, a shift in behavior, such as lying around and seeming uncomfortable, suggests that the ulcer might not be the sole issue affecting Sonny.

Given Sonny’s age and the evolution of his condition after years of treatment, Dr. Paola strongly recommends a veterinary visit as soon as possible. An in-depth oral examination under sedation or anesthesia may be necessary to ensure the diagnosis of eosinophilic ulcer is accurate and to rule out other painful oral conditions such as dental disease, feline chronic gingivostomatitis, tooth resorption, oral tumors, or secondary infections.

Persistent or atypical ulcers, particularly those that are localized or do not respond to treatment as expected, may require a biopsy since various diseases can exhibit similar external characteristics. Previous treatments may have included corticosteroid injections, which typically help improve eosinophilic lesions, but long-term steroid use in older cats necessitates careful consideration due to changing risks and benefits as the cat ages.

It is also crucial to explore potential underlying causes, especially through stringent flea control and, when appropriate, conducting a dietary elimination trial. Dr. Paola likens the ulcer to smoke rather than fire; addressing the visible symptoms may provide temporary relief, but identifying the source of inflammation is key to preventing future occurrences. For now, she advises prioritizing a thorough health assessment for Sonny, rather than relying solely on supplements. While his ongoing appetite is a positive sign, cats often hide their pain well, and a noticeable change in behavior can indicate discomfort. A comprehensive examination, including oral evaluation, blood tests, and discussions about the need for dental radiographs or biopsies, is recommended as the next logical step.
