Thank you for answering my questions!

There are a couple of possibilities here. The first one is allergies. As the weather is getting warmer, there have been more allergens in the air than in the wintertime. If all you are seeing is watery eyes, it's quite possible your kitty is suffering from a mild reaction to allergies. Some vets will recommend over-the-counter plain Benadryl to help with the symptoms of seasonal allergies. The dose for kitty cats is 0.25-0.5 mgs/lb every 8-12 hours as needed. You might try that and see if it helps the allergies at all, and if you are seeing a worsening of the problem, or it is not improving, you can see your vet for a different medication.

Alternatively, you cat could have gotten something into her eye that's irritated it. Since it's only watery, it's unlikely that there is damage to the eye. However, if it becomes red or swollen, you will want to take her into the vet to have them stain the eye to see if there is a small tear to the cornea. Depending on the severity of the irritation, they can provide you with steroid drops or antibiotics to help it clear up.

In the mean time, you can gently wipe her eyes with a warm, moist washcloth or paper towel to help clear the fluid from her eyes and prevent her from developing eye crusties.

If you have any follow-up questions or concerns, please hit reply, and I would be glad to address them for you. Otherwise, I hope this information was helpful to you and that your poor kitty starts to feel better soon!
