chronic uri signs to watch

so my black cat duke has been sneezing for like two weeks now. started clear but now its getting a bit greenish and he is low key lethargic. my white cat ivy has been sneezing clear for a month but she is still zooming around the house.

im not sure if duke is just dealing with a chronic uri or if this is a viral blip that will pass. ivy seems fine energy wise. is there a clear line between "wait and see" and "go to the vet"? duke is 3 and ivy is 2.

Hi Dave. I am so sorry about Duke. My rust cat Copper is 5 and diabetic, so his immune system is already a bit compromised. I found out in diabetes and uri frequency that metabolic issues can make a minor virus linger longer or turn into something bacterial faster.

I would not wait if the discharge is green. Green usually means bacteria have moved in. For Ivy, if it is clear and she is eating, it might just be the seasonal thing. But keep an eye on her appetite.

Agreed with the green discharge point. I had a similar situation with my 9-year-old tabby Smudge. He got a cold that looked viral at first but then the nose got crusty and he stopped grooming. It turned out to be a secondary bacterial infection.

You can check out viral vs bacterial uri signs for some of the specific markers. Viral is usually clear/white and watery. Bacterial is yellow/green and thick. If Duke is lethargic, that is a red flag that his body is fighting hard.

Gentle reminder that lethargy combined with colored discharge is not something to monitor at home for much longer. I wrote about the timeline in how long is too long for sneezing?. Generally, if a cat is not acting like themselves after 48 hours of symptoms, it is time for a professional check. Duke sounds like he needs one today. Ivy sounds like she might just be a dusty nose, but she is young so it is safer to watch her closely.

I think you are right to be worried about Duke. My tuxedo Ink is 4 and gets these weird sinus headaches when the pollen count is high. But his eyes stay clear and he still hunts the feather wand. If Duke is not playing, it is not just allergies.

Maybe look at allergies or bugs? to rule out environmental stuff, but the lethargy is the key differentiator here. I would call the vet before the weekend.
