Short answer

Yes, plain cooked egg without salt, butter, or seasoning is safe for a nursing cat and makes a good source of protein to support milk production. Make sure it is fully cooked rather than raw, because raw egg whites carry both salmonella and biotin-deficiency risks. A tablespoon or two mixed into her regular food a few times a week is plenty — she does not need it daily.

Safe cooked (no salt/butter). Eggs are a great protein source. Raw egg whites carry a salmonella and biotin risk.

Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.

Cooked eggs is not toxic to cats. The real limit is calories, fat and salt, so treat it as a small extra alongside the normal ration rather than a meal in itself.

There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.

Why these cautions matter

A heavy salt load drives up thirst and urination, and in the worst cases leads to sodium ion poisoning, which is a genuine emergency.

Rich, fatty food is the classic trigger for pancreatitis, a painful inflammation of the pancreas that usually needs veterinary treatment rather than rest alone.

Raw animal protein carries Salmonella and E. coli risk, and those bacteria can spread to the people in the household too.
