Quorn is a human meat substitute made from mycoprotein. Cats are obligate carnivores, so they need a complete cat food built around animal-source nutrients, not a fungi-based meat substitute. In other words, Quorn is not a cat food and should not be offered on purpose.
The bigger problem is the prepared product. Quorn meals, nuggets, sausages, and similar meatless foods can include onion, garlic, onion powder, garlic powder, salt, and other seasonings. Those ingredients are a poor fit for cats, and allium ingredients can damage red blood cells. For related examples, see Can Cats Eat Meatballs?

What If Your Cat Took A Small Bite?
If your cat stole a tiny bite of plain cooked Quorn, they will often be okay, but monitor for vomiting, diarrhea, drooling, belly pain, lethargy, or loss of appetite. If the product had onion or garlic, or if your cat ate more than a bite, call your vet or a pet poison line the same day.
What Is Safer?
If you want to share food, choose a small amount of plain cooked meat or a cat treat that is complete and balanced. Cornell notes that treats are not nutritionally complete and should stay limited; cats also need nutrients found in animal products, including protein and amino acids such as taurine.
Bottom line: a plain accidental nibble is different from feeding Quorn as a treat, but it is still not something to make part of your cat’s diet.
