Our Boo is just like your cat SWOT. She is definitely a puker of mostly whole or partly digested kibble - (is it still called kibble when it's for cats?) She is otherwise healthy and sweet. (Well, she has a tendency to want to pee on anything left in the floor - especially plastic bags - but that just makes us keep things picked up.)
We did free feeding, but decided maybe she was eating too much...she was kind of tubby. So now we give her the recommended amount of food on the bag each day. She's still puking, but not nearly like she had been. So if you leave food out all the time, try switching that up to set meal times.
We'll try raising the food bowl! Maybe that'll help.
