Cats can technically eat Spam as it is not toxic to them since it is made from pork. However, Spam is very high in sodium and fat, which makes it unhealthy and unsuitable as a regular part of a cat's diet. Feeding Spam to cats can lead to health problems such as obesity, hypertension, kidney issues, and pancreatitis. A small taste occasionally is unlikely to harm a cat, but it is best to avoid giving Spam and instead offer treats made specifically for cats or small portions of plain, unseasoned meat like cooked turkey or chicken. Always consult a veterinarian before introducing any human food to a cat’s diet.
