My cat's left eye has been squinty the past couple of days and a little watery. It sometimes goes away but comes back again throughout the day. She seems more tired than usual for the most part, but she's still been eating regularly and drinking water. Even though she's been more tired than usual, she's still had some bouts of playful energy, but not for as long as usual. I figure she just has a cold and if it doesn't get better in the next 2 or 3 days, I'll take her to the vet. I don't want to stress her out by putting her in the cat carrier (i'm sure THEN she would have a TON of energy), and taking her out, if it's just a cold. Does this sound like anything serious that I should really worry about, though?
