Hel, what is this weird sound she is making?

My cat was neutered 9 days ago. She is an older cat. She hasn't been herself. She is drinking, but very little reading. I went this evening and got her can food with the gravy. She has it almost completely gone. [emoji]128513[/emoji] But since yesterday she is making this sound, it's between a sneeze and the hiccups. If she doesn't improve by morning, I'm calling vet FIRST thing tomorrow morning.

Eating, not reading!

I think you've answered your own question. Anything anyone could say at the moment would be pure speculation.

You need to get her to a vet. The not eating is a worry.
