This is Cecil. He's an 11-month old rescue that I've had from the time he was about 3 months old. He's spayed, current on all of his shots, and has always been a healthy cat. He's very energetic and happy.
However, from the time I adopted him, I've always noticed a buildup of dirt in his nostrils. Since he has no breathing or sneezing issues, I just assumed he was putting his face too close to the litter when digging, and I usually wipe it with a tissue. Over the weekend I've noticed a reddish-brown crust in his eyes, followed soon after by a transparent film over his eyes. He does not seem troubled by this. I haven't noticed any excessive blinking or a change in his behavior. I'm wondering if this is a sign of an allergy? Does anyone have experience with this?
Note: I do plan to take him to the vet, but the office was closed over the weekend and today, since it's a holiday. Assuming we don't get the predicted blizzard tomorrow, I'm planning on making an appointment for him, but I'd like to have some idea of what I could expect.
