Cats pupils are different sizes after vet visit

Thanks for reaching out. It's understandable to be worried if your cat's pupils are suddenly different sizes, especially after a vet visit. This condition is known as anisocoria, and there are several possible reasons it could occur.



In some cases, anisocoria in cats might be a temporary reaction to eye drops or medications given during the vet visit. These can cause one eye to respond differently to light than the other. Typically, this effect wears off after a few hours.



However, if your cat displays additional symptoms, such as squinting, redness, a noticeable difference in vision, or if the pupils don’t return to normal within a day, it might indicate a more serious issue like eye trauma, neurological problems, or an underlying systemic condition.



For now, ensure your cat is comfortable and doesn’t have access to bright lights, which can be bothersome. Keep an eye on any changes in behavior or coordination. If you notice things like lethargy, vomiting, or disorientation alongside the unequal pupils, it's important to get in touch with a veterinarian as soon as possible.



I recommend booking a video consult with Dial A Vet so we can discuss your kitty's specific situation more thoroughly.
