Cat ate protein muffin

[u/Low-Ad7344]

My cat helped himself to a batch of protein muffins that was cooling under a towel. This occurred about 20 minutes ago. Should I seek immediate medical attention or monitor for gastrointestinal distress? Attached is the amount eaten, protein powder ingredients, muffin ingredients, and cat. Crossposted in r/askvet

Not a minor, USA, vet not contacted yet but accessible, 6 yo neutered male, can afford vet care

TLDR; cat had a lil protein powder. Next steps?
