Thanks for using Petco Pet Education Center, formerly Petcoach! This can be due to weakness, a neurologic condition, severe dehydration, decreased mentation, among many other reasons. I would recommend that you have Rio evaluated by a veterinarian who can examine Rio and gather more information to know what would be the next most appropriate steps. I am hoping they can help Rio recover from this!

I am sorry to hear about your kitty. There could be a number of causes for a white appearance to the eye, including edema in the cornea/surface of the eye, uveitis (inflammation within the eye), Trauma to the surface of the eye, and more. Your kitty needs an in person exam by a veterinarian with an ophthalmoscope to determine the cause of the cloudiness and treat accordingly.

The white in the corner of his eyes is actually called his third eyelid. This is a normal structure that all cats have. However, his third eyelids are elevated at this time. This can indicate problems with the eyes or possibly general ill thrift ( or not feeling well). I would highly encourage you to have him evaluated by your veterinarian soon as possible. They may recommend blood work to help determine a diagnosis. Best of luck and I hope he improves soon. Thank you for using Pet Coach.

The white part is Sully's third eyelid, and it normally only comes out when a cat's eye is closed. If it shows when the eye is open, it's a sign of a problem like an eye infection. Any eye infection would cause him to keep the eye partially closed as well because it's sensitive to light. Any eye problem is considered an emergency because leaving it untreated can lead to vision loss. Please take him into a vet now. Best of luck.

My cat has glassy eyes. Is this a sign of cataracts or other issues?

Thank you for using Petco Pet Education Center, formerly Petcoach and congratulations on your new pet! Glassy eyes may refer to cataracts, which are opacities in the lens of the eye. At a certain stage these can result in blindness. A photo of Puma's eyes would be great to help determine if this is the case. Cataracts can be treated, but it may not be necessary. I hope all is well!

My cat's eye is cloudy, lethargic, breathing fast. Emergency?

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be due to an eye injury or conditions such as a corneal laceration, corneal ulcer, conjunctivitis, dry eye (also known as KCS), among many other conditions. I highly recommend that you have Lewi evaluated by your veterinarian for further assessment and treatment. Further therapy would be based on the findings. Good luck and best wishes!

My cat's eye looks reflective or cloudy. Is it serious or normal?

Thank you for submitting your question regarding your cat. I recommend that he sees a veterinarian. He seems to have an opacity in his eye. This can be on the cornea (surface of his eye) or on the lens. He could have a scratch across his eye or even a scar. If the problem is on his lens, then a cataract is a possibility. His veterinarian will examine his eye with a special instrument called an ophthalmic scope. Some tests may be recommended as well. I hope this information helps!

My 12-year-old cat's blue eyes changed. Is it age or a health issue?

This can be a sign of a systemic disease. The inflammation in the eye can be a serious problem that needs treatment. I recommend a veterinary exam and lab testing to diagnose the problem and start him on the appropriate treatment. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Loty.

My cat's eyes glow in photos. Is this normal? Should I see a vet?

Thanks for using Petco Pet Education Center, formerly Petcoach! She is gorgeous! Her eyes are likely reacting to the light and her surroundings and this is unlikely to be an actual issue. I would continue to monitor her for signs of eye discharge or discomfort and have her evaluated if any of these are seen. However, I think she is most likely just fine. Good luck!

My cat's eye whites are brown/red, and she's vocal. Is it serious?

Hi there and thank you for posting this picture. The whites of the eyes, or sclera, look to me like some normal age related pigmentation changes. I am not overly concerned by what I see in the picture. However, pictures are never as good as hands on examination. I would encourage you to have Vriska examined by your veterinarian. I do not feel this is an emergency and a routine appointment would be appropriate. Best of luck and thank you for using Pet Coach.

My cat has red, puffy eyes and is sleeping a lot. What's wrong?

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. Based on your description, Rome may be dealing with an infection (bacterial or viral). I would recommend having Rome examined by a veterinarian so that the most appropriate diagnostic and treatment recommendations can be made. Rome may need a course of an antibiotic to help treat this along with eye drops if there is evidence of infection in the eyes. If he is sleeping more than usual, he may be lethargic from the infection. I would make sure he is eating and drinking ok. If not, then I would have him seen sooner rather than later. I hope this helps guide you in the right direction! Please let me know if you have any other questions or concerns.
