Stomach Spasm?

[Tella]

Hi y’all. This just started happening a couple hours ago. My 6 month old female ragdoll (who got desexed 2 weeks ago and is on a e-collar) has been having a couple stomach spasms (?) after she eats her dry or wet food. It doesn’t happen every single time but sometimes. It’s like her belly pumps in and out.
I’ve uploaded a short video of it happening here:
Is this serious? Should I take her to the vet?

I'd email the video link to the vet. The vet would better know what is happening.

It may be hiccups after eating because of the collar holding her head at a weird angle. If it has been two weeks that should be the time to take it off. I have never used a collar on my cats and have never had a problem. They start healing well in a week after surgery. call your vet and see if you can take it off, then observe her.
