Can rats eat marshmallows?

Can rats eat marshmallows?

We say no. The CoFID entry in the table below shows marshmallows are 64.5 g sugar per 100 g (3.5 oz), with no recorded fibre. Their low fat figure isn't a health point: a sweet can be low in fat and still a poor choice. The UK RSPCA advises keeping sugary foods limited, and RSPCA Australia recommends avoiding sweets and "sticky foods that could be a choking hazard." Walkerville Vet in Australia also tells owners to avoid lollies (sweets).

Is the main issue sugar or stickiness?

Both, and they are different points. Sugar is about what the food contains: rats gain weight easily, and sweet foods crowd out balanced ones. Stickiness is about how it behaves in the mouth. The Rat and Mouse Club of America says thick, gooey or very sticky foods are the main choking risk for rats, with peanut butter the most common culprit, and that rats cannot vomit. We aren't claiming every tiny crumb will cause choking. We're saying there's no need to choose a sticky sweet when a piece of vegetable or some of the normal ration works as a reward.

Are mini, vegan or toasted marshmallows better?

Read the exact packet rather than judging a whole sweet aisle from one product. If you were thinking of chocolate or raisins, those are a no too.

Can rats have graham crackers?

A tiny corner now and then, at most. VCA Animal Hospitals list whole grain crackers among occasional treats for rats, once or twice a week, keeping treats under 5 to 10% of the diet. Graham crackers (similar to UK digestive biscuits) are sweetened, so they sit at the sugary end of that list. A s'more, with marshmallow and chocolate, is a no.

My rat already ate a marshmallow

1. Remove the rest. Take away remaining sweets and check the packet for chocolate or other coatings.
2. Watch the rat. Drooling, pulling the head back in a gagging motion and flattened ears are choking signs, the Rat and Mouse Club of America says. Repeated pawing at the mouth is another.
3. If it can breathe, keep it calm. Leave it quiet, check often and ring your exotics vet for advice; most rats clear a blockage within one to four hours.
4. If it can't breathe, go now. Struggling to breathe, collapse or marked distress means an emergency vet immediately.
5. Don't force anything in. Never push water or more food into its mouth, and don't try a home remedy.
6. If it seems fine, carry on. After a small taste, watch normal eating and behaviour, and ring your exotics vet if you're unsure.

The food facts, not a rat serving size

These are values per 100 g (3.5 oz) of the named food, from Public Health England's CoFID 2021 dataset, table 1.3 Proximates. They describe the food, not an amount to feed a rat, and no rat-specific toxicity limit is taken from them.

What to give instead

For a sweet reward, a piece of apple without the seeds or a little ripe peach works, each about the size of your rat's ear. For a crunchy one, try plain popcorn. If you use peanut butter for training, spread it very thin. The RSPCA recommends a food made for rats as the staple, with fresh variety inside the normal allowance. Our rat diet and nutrition guide, the rat food checker and the safe food list for rats cover the rest, and the pet rat care hub links every guide.
