My cat has red eyes. Is it allergies, stress, or needs a vet?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 7 years and 11 months old | 13 lbs

Does this require medical attention or is it just allergies or could it be stress? My cat does not seem bothered by it at all. I'm thinking it may be stress caused from our newborn baby crying or maybe an ivy plant she got into recently. It started about a week ago and seems to be on her other eye as well but no hair loss and not as red on the second eye.

If Cali is behaving normally otherwise, you can try using an e-collar (cone) on her to prevent scratching or rubbing. This may allow time for healing. Also, check her over for fleas or flea dirt. If she is sensitive, just one flea bite could make her very itchy. A pheromonal product, such as Feliway spray or diffuser, may decrease any stress or anxiety due to your new addition (Congratulations, by the way!). Keep the Ivy out of reach if possible. While not high on the toxicity scale, ingestion or chewing of a leaf or two may cause irritation in and around the mouth and/or GI upset. Monitor for worsening of symptoms, squinting of the eye(s) or discharge. See your veterinarian for a physical exam to address non healing or additional symptoms.
