Not recommended

Why: Silverfish are not venomous, but they are not a food for cats. They live in damp places and can carry bacteria, and they are often found where insecticides have been used. A cat that hunts them is usually fine, but do not offer them.

If your cat ate silverfish: One silverfish is usually harmless. Watch for an upset stomach. If the area was recently sprayed with insecticide, call your vet.
