Can Cats Eat Deviled Eggs?

No. Keep deviled eggs away from cats. The cooked egg white is the least of the worries. The filling is mashed yolk beaten with mayonnaise, mustard, salt and pepper, topped with paprika, and many family recipes add onion, garlic powder, pickle relish or bacon.
Why Deviled Eggs Are a Problem for Cats
The filling is rich. Egg yolk and mayonnaise together are mostly fat, and the ASPCA notes that the oils and fats in nuts can cause vomiting and diarrhea, and potentially pancreatitis in some pets. Some cooks fold in sour cream or cream cheese, which adds dairy. The ASPCA explains that pets lack much lactase, so dairy can cause diarrhea.
Seasoning is the next problem. Deviled egg filling is salted, and relish, bacon and mustard add more salt. The ASPCA warns that too much salt can lead to thirst, vomiting, diarrhea, tremors and seizures. Many recipes call for minced onion, onion powder, garlic powder or chives. The Merck Veterinary Manual says cats are the most susceptible species to onion and garlic poisoning, and powders are among the concentrated forms most often to blame. WSAVA lists onions, garlic and chives among foods toxic to cats.
Paprika and cayenne add a sharp, spicy dusting that a cat does not need. Hot sauce, sriracha and jalapeno versions are common at parties and add more chili, salt and sometimes garlic.
The egg itself, cooked and plain, is a different matter. Cornell's Feline Health Center describes cats as obligate carnivores that rely on nutrients found in animal products, and a small bite of plain cooked egg is an animal protein. The ASPCA says raw eggs can carry bacteria such as Salmonella, so only fully cooked egg with nothing added makes sense to share.
Signs to Watch For
Most cats that steal a deviled egg get stomach trouble within hours, with vomiting, diarrhea or a skipped meal. If the filling had onion, garlic or chives, the Merck Veterinary Manual says signs of red blood cell damage usually show up several days later. Watch for weakness, a poor appetite, fast breathing, pale or yellow gums and reddish urine.
What to Do If Your Cat Ate Deviled Eggs
If the filling had onion, garlic or chives, or your cat ate more than one egg half, call your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 right away. Do not try to make your cat vomit unless a vet tells you to. Tell the vet what went into the filling.
If your cat has pancreatitis, a food allergy or another medical condition, ask your veterinarian before offering egg in any form.
Common Questions
Can cats eat hard-boiled eggs?
Plain hard-boiled egg, with no salt or seasoning, can be shared in a small amount. Cut a piece about the size of your thumbnail and count it toward your cat's daily treats, which WSAVA puts at about 22 to 25 calories for a 10-pound cat. The ASPCA warns that raw eggs can carry Salmonella, so make sure the egg is fully cooked.
Can cats eat egg yolk?
A small bit of plain, fully cooked egg yolk is not a problem for most cats, but it is rich in fat, so keep the piece small. The yolk in deviled eggs is a different thing, because it is mixed with mayonnaise, mustard, salt and often onion.
Can cats eat paprika?
There is no reason to give a cat paprika. It is ground dried pepper, and spice blends sold as paprika or seasoning salt may include garlic or onion powder. The Merck Veterinary Manual says cats are the species most sensitive to onion and garlic. A dusting licked off a deviled egg is unlikely to be the main concern, but the filling under it can be.
What happens if my cat eats a deviled egg?
Many cats will vomit or have soft stool within a day from the mayonnaise and egg yolk. If the filling contained onion, garlic or chives, Merck notes that signs of red blood cell damage such as weakness, pale gums and reddish urine can appear several days later. Call your veterinarian and describe the recipe so they can tell you what to watch for.
Can cats eat raw eggs?
No. The ASPCA says raw eggs can carry bacteria such as Salmonella and E. coli, which can make both pets and people sick. It also notes that raw eggs can interfere with vitamin absorption, which may affect skin and coat. If you share egg, cook it all the way through and serve it plain, with no butter, oil or salt.
