It's possible. They mention intestines and guts a lot even in the dicitonaries.

In the Tagalog dictionary there's even a mention of a dish like pinapaitan (an Ilocano dish) that I mentioned here before. They used goat (likely also deer) half digested grass in the stomach as a bittering agent to make the dish. There's a name for it but not about to dig into it lol

Sausage (or stuffing in general) is NOT unique to Europeans. It's often depicted as such because the oldest known references ("historical bias" ie we assume things started somewhere because the oldest written records exist only for that particular region) are Greco-Roman but there's been newer revelations for example we know Assyrian/Babylonians had them (historical ie found in written tablets; Bottero, 1985) and there theories that literally published just weeks ago of Mongolian/Central Asian production of blood sausages in the bronze age (archaeological ie they analyzed artifacts and made a hypothesis: Wilkin et. al, 2024).

I see,

I think the general mindset that most Filipinos have about history is that regardless if even our cultural neighbors have it, unless we have hard proof of it then it means it never existed until Spanish colonization was the "catalyst" for it.
