One other thought ... sometimes Thelma's throat will get irritated after struggling to expell a hairball. My old vet gave her a round of steroids and it helped her throat recover from a bad bout once.

It could also be the Spencer is simply eating too fast (common in multicat households.) Whenever I treat my cats to tuna, Thelma gobbles hers so fast she immediately vomits it back up.
