so today i noticed by kitten ( 6 months old) eyes were different sizes and is way more noticeable when hes in a room with a lot of light or outside, it was fine early this morning and the only thing i could think of that would cause that is that late this morning he was playing and hit his head on the coffee table when he turned around to run under it but he kept playing and everything seemed fine, he's not showing any symptoms of something being wrong and is still eating,drinking, playing and running around as normal. I've called the vet and explained the situation and they've said to just monitor him for 24hrs and see if anything changes with him, Should i be worried? they didnt seem to think it was that big of a deal considering how young he is but ya know, still worried a bit.
