Hello, I'm Dr. Deb and will do my best to help you today.
I'm sorry for this concern for Brumas.
There actually could be several different reasons why a cat might start to sneeze including an early upper respiratory infection (uri), dust (secondary to litter or things in the environment), polyps in the nose, or foreign bodies...just to name a few examples.
I wouldn't consider this to be an ER type of situation, though, since he's eating. It's quite possible that this will be a transitory episode but if he should still be sneezing by Monday and/or other signs develop (such as weepy eyes), then a vet visit may be prudent.
I hope this helps. Deb
You're more than welcome.
Always best to be safe in these situations and better to ask than to worry:) So glad you did.
Best of luck with him. Kind regards, Deb
And, thanks for the rating; it's greatly appreciated.
Take care, Deb
