Yes, rats can eat eggs, as long as they are cooked. Plain hard-boiled or scrambled egg is one of the protein treats the RSPCA and PDSA both name for pet rats. Give about half to one teaspoon per rat, once or twice a week, counted as part of the day's food rather than on top of it. Never feed raw egg.
| Safe? | Yes, cooked |
|---|---|
| How much | Half to one teaspoon (2.5 to 5 ml) per rat |
| How often | Once or twice a week |
| Best served | Hard-boiled or dry scrambled, plain, cooled |
| Watch out for | Raw egg, salt, butter, oil and weight gain |
Are eggs good for rats?
Yes. Rats are omnivores, so a little animal protein is natural for them. PDSA lists egg alongside lean meat, a mealworm and lentils as an occasional treat, and the RSPCA says cooked egg can be offered as part of the daily food allowance. Its soft texture also suits older rats.
The base of the diet should still be a complete rat nugget. Burgess suggests 15 to 25 g (0.5 to 0.9 oz) of nuggets per rat a day, and treats like egg come out of that allowance. Our rat diet guide shows how it all fits together.
How much egg can a rat have?
About half to one teaspoon of cooked egg per rat, once or twice a week, is the amount vet-reviewed advice from The Vet Desk gives. That is roughly a piece the size of your thumbnail. One egg covers a group of four to six rats. If your rats are already round, give it less often.
The RSPCA suggests giving a cooled, hard-boiled egg whole and unpeeled now and then. Rolling it, cracking it and picking out the inside keeps a group busy for ages, and it counts as their egg treat for the week.
How to prepare eggs for rats
- Cook it through. Boil for about ten minutes until the yolk is firm, or scramble in a dry non-stick pan with no butter, oil or milk.
- Keep it plain. No salt, pepper, cheese or sauces.
- Cool it. Let it come to room temperature so nobody burns a mouth.
- Portion it. Chop a teaspoon-sized piece per rat, or hide pieces for them to find.
- Clear up. Take away any egg left after a few hours, as it goes off quickly in a warm cage.
Raw egg, yolk, white and shell
Skip raw egg. Raw egg can carry bacteria that cause infection, and cooking removes that risk. Both the yolk and the white are fine once cooked; the yolk carries most of the fat, so rats watching their weight can have more white than yolk. Cooked shell nibbled while peeling is harmless. Fried egg, omelette and egg mayonnaise carry fat and salt that rats do not need.
Who should go easy on eggs?
Overweight rats should have egg less often, and if your rat has a health condition or is on a special diet from the vet, ask before adding protein treats. A pregnant or nursing doe eats far more than usual, so a little egg is a good extra for her.
Other protein treats to try
Mix things up with mealworms, a flake of plain cooked salmon, or cooked peas and lentils. Dairy is a less useful choice: see can rats eat cheese. For the full list, see what rats can eat, and our pet rat care hub covers everything else.
Questions owners ask
Can rats eat raw eggs?
No. Raw egg can carry bacteria that make rats ill, and cooking removes that risk. Always boil or dry-scramble the egg first, with no butter, oil, milk or salt, and let it cool before you offer it.
Can rats eat scrambled eggs?
Yes, if they are cooked plain in a dry non-stick pan with no butter, milk, oil or salt. Give about half to one teaspoon per rat once or twice a week and clear away any leftovers within a few hours.
Can rats eat eggshells?
Clean, cooked shell is not harmful, and rats will nibble some while peeling a whole boiled egg. There is no need to feed shell on purpose: a complete rat nugget already supplies the calcium they need.
Can baby rats eat eggs?
Yes, once they are weaned and eating solid food well. Soft scrambled egg is easy for young rats to manage. Keep the portion small, about half a teaspoon each, and introduce it slowly.
