Yes, rats can eat cherry flesh as a small treat, as long as you take out the stone first. Give about half a fresh cherry per rat, around once a week. Never give the stone (pit), stalk or leaves: PetMD lists fruit seeds and pits among foods rats should not have. Skip glacé, maraschino and tinned cherries, which are soaked in sugar.

|---|---|
| How much | Half a cherry (about 3 to 4 g, 0.1 oz) per rat |
| How often | About once a week |
| Best served | Fresh, washed, stoned, halved |
| Watch out for | Stones, stalks, sugar-soaked cherries, sticky juice |
Are cherries safe for rats?
The flesh is. We could not find a vet or charity page on cherries for rats specifically, so this page reasons from what good sources say about stone fruit. A vet-reviewed guide from The Vet Desk says peach flesh is safe in moderation once the stone is removed, while naming cherry and peach pits among things rats should never have. Cherries are sweet, so they belong with other fruit as an occasional treat.
Why the stone, stalk and leaves are a no
Cherry stones, like other stone fruit pits, contain amygdalin, which releases cyanide when crushed. The Vet Desk notes there are no reports of seed poisoning in pet rats, but it still puts cherry pits on its never list, and a rat's teeth are made for cracking things, so we take the stone out every time. The stalks and leaves of cherry trees contain the same compounds, so keep rats away from cherry tree prunings too.
If your rat has cracked and eaten cherry stones, take any others away and watch closely. Ring your vet straight away if you see fast or difficult breathing, weakness, wobbliness or a rat who goes very quiet. One swallowed whole stone is less of a worry than several crunched ones, but call your vet if you are unsure.
How much cherry can a rat have?
About half a cherry per rat, once a week. Burgess suggests a piece of fruit about the size of a rat's ear as a good fruit portion, and PetMD advises giving fruit in smaller amounts than vegetables because of its sugar. Too much fruit can cause soft droppings and weight gain.
Fresh, dried, tinned and glacé cherries
| Form | OK? | Notes |
|---|---|---|
| Fresh sweet or sour cherries | Yes, stoned | Halve and remove the stone and stalk |
| Frozen pitted cherries | Yes, thawed | Check every stone is gone |
| Dried cherries | Rarely | Concentrated sugar, often sweetened, and sticky |
| Glacé, maraschino, tinned in syrup | No | Soaked in sugar |
| Cherry pie, jam, cherry-flavoured sweets | No | Sugar and fat |
Other fruit to try
Lower-sugar treats include blueberries and strawberries. Other stone fruit, such as peaches and plums, follow the same "stone out" rule. See our safe food list for rats, the rat diet guide and our pet rat care hub.
Questions owners ask
Can rats eat cherry pits?
No. Cherry stones contain amygdalin, which releases cyanide when crushed, and rats are good at cracking hard things. Always remove the stone. If your rat has crunched several, ring your vet.
Can rats eat dried cherries?
Only rarely. Dried cherries are high in concentrated sugar, many are sweetened, and they are sticky. A small piece of a plain dried cherry now and then is the most a rat needs.
Can rats eat maraschino or glacé cherries?
No. They are preserved in sugar syrup and often coloured, which gives a rat nothing useful. Stick to fresh cherries with the stone taken out.
Can rats eat sour cherries?
Yes, with the stone removed. Sour cherries follow the same rules as sweet ones: about half a cherry per rat, around once a week. Some rats dislike the sharp taste.
