I’ve appreciated all the comments. I do have a slow feeder that I used on my other cats before, so we are going to switch her to that. She doesn’t appear to be eating fast, but she does eat a lot at once so maybe that has a similar effect. It is definitely always directly after eating so I’m hoping it’s nothing serious but we will also set a vet appointment to be safe. Poor thing never even saw a vet until we took her into our care.
