eyes

Question
I just noticed one of my cat's eyes is dialeted and the other one is not, what is wrong?  

Answer
This could indicate some sort of problem with the dilated eye but I don't have enough information to help you. Is there any discharge? Is the corneal tissue red or irritated? Is the cat otherwise acting normally, walking normally? If it isn't an eye irritation, the one thing that comes to mind immediately is a fall and a possible blow to the head, but if he/she is not showing other signs of illness/trauma, I would just watch it carefully. If it does not return to normal by morning you should probably call your vet.

Hope this is some help but it is very hard to address this kind of situation without seeing the cat.
