Can Hamsters Eat Eggs? Cooked Only, and Rarely

What the veterinary and care guides say

Merck says a commercial rat or mouse pellet containing 15 to 20 percent protein meets a hamster's needs, and that extra vitamins are usually unnecessary. VCA Animal Hospitals likewise says pet rodents should eat mainly pellets, about 90 percent of the diet.

Neither of those pages mentions egg. Two hamster care charities do: PDSA lists small pieces of boiled egg among occasional treats, and Wood Green says plain cooked chicken or boiled egg can be offered occasionally as a protein-rich treat. Merck says treats should stay within 10 percent of the diet, which is the limit any egg would have to fit inside.

Why raw egg is a poor idea

The ASPCA says raw eggs and raw meat can contain bacteria such as Salmonella and E. coli that can be harmful to pets and to people alike. It also says raw eggs contain an enzyme that can interfere with absorption of certain vitamins, leading to skin and coat problems.

That page speaks about pets in general rather than hamsters, but the reasoning holds for a small animal. Raw egg also leaves bacteria on your hands, the bowl and the cage floor, so skip it entirely.

If you decide to offer cooked egg

Use plain, fully cooked egg with nothing added: no salt, butter, oil, milk or seasoning. Wood Green suggests keeping treats about the size of your hamster's ear, once or twice a week, and VCA also suggests treats no more than once or twice a week. Treat egg as one of those occasional extras rather than a regular part of the week.

Hamsters store food in their cheek pouches and hide it in the cage, according to Merck. Check the hamster cage corners and bedding after treat time and remove any leftover egg the same day, because a roomy large hamster cage gives a hamster plenty of places to hide a store.

Do not add egg to fix a protein worry

Merck says hair loss in hamsters can be linked to too little protein in the diet, among other causes. If your hamster has thinning fur, a patchy coat or low energy, adding egg is not the answer, and the cause needs a veterinarian who treats small mammals.

Check first that the main diet is a proper hamster or rodent pellet and that seeds are not being picked out in place of it. Merck says seeds should be limited because hamsters may choose them over their balanced pellets, and VCA says a strict seed diet is high in fat and poor in nutrition.

Watch the droppings after any new food

Merck says diarrhea, often called wet tail, is seen often in hamsters, and that stress from diet changes can make it more likely. Signs include wet fur around the tail, low energy, poor appetite and weight loss.

A hamster with these signs needs a vet who treats small mammals promptly, since Merck warns that some antibiotics can be deadly to hamsters and that a veterinarian must prescribe any medicine. Try any new food on a day when you can check the droppings over the next day or two.

Better choices and when to see a vet

Vegetables are the better daily fresh food. VCA lists leafy greens and yellow or orange vegetables as acceptable and says to avoid iceberg lettuce and celery. Fresh, clean water should be available around the clock and changed at least daily.

Call your vet if your hamster stops eating, has loose droppings or seems lethargic after eating anything new.
