Yes, guinea pigs can eat strawberries as a treat. One medium strawberry, washed and halved, once or twice a week is plenty for each guinea pig. Strawberries are on the PDSA and Burgess lists of safe fruit and are one of the best fruits for vitamin C, but they still contain sugar, so keep them as a small extra.
| Safe? | Yes, as a treat |
| How much | 1 medium strawberry, or half a large one |
| How often | Once or twice a week |
| Best served | Fresh, washed, green top cut off |
| Watch out for | Spoiled berries, soft droppings, red-stained chins |
Are strawberries good for guinea pigs?
Yes, in small amounts. The PDSA and Burgess both list strawberry as a safe fruit, and both say fruit should be a small treat because of its sugar. VCA warns that too much fruit can upset the gut bacteria and cause serious diarrhoea.
Strawberries stand out among fruits for their nutrition. Worked out from the Guinea Lynx food chart, they have about 59 mg of vitamin C per 100 g (3.5 oz) and about 5 g of sugar. That is six times the vitamin C of blueberries or banana, with less sugar than either. One medium strawberry goes a good way towards a guinea pig's daily need of 10 to 50 mg, given by VCA. Even so, fruit should never be the main vitamin C source: bell pepper and leafy greens do that job every day without the sugar.
How many strawberries can a guinea pig eat?
One medium strawberry, or half a large one, per guinea pig, once or twice a week. Don't give other fruit on strawberry days. The rest of the diet stays the same: unlimited hay, about one cup (a teacup-sized handful) of veg a day and about a tablespoon of pellets, as our guinea pig diet guide explains.
How to prepare strawberries
- Choose firm, ripe berries. Throw out any that are soft, bruised or gone off; strawberries spoil fast.
- Wash them well. Rinse under cold water, since strawberries are often sprayed while growing.
- Cut off the green top. Our sources cover the fruit, so we give just the red part.
- Halve or quarter it. Smaller pieces are easier to share fairly between two guinea pigs.
- Clear up leftovers. Remove uneaten pieces within an hour or two.
Give strawberries on the same day you buy or pick them. Vitamin C fades after picking, as Guinea Lynx notes, so a fresh berry is worth more than one that has sat in the fridge for a week.
Fresh, frozen, tops, dried and flavoured
- Fresh: yes, the best choice.
- Frozen: yes, fully thawed.
- Green tops and leaves: we'd cut them off.
- Dried strawberries: no.
- Jam, yoghurt, milkshake, sweets: no.
Who should skip strawberries?
Leave them out for guinea pigs that are overweight, have a sensitive stomach or loose droppings, and for babies not yet fully weaned.
What to offer instead
For another berry, try blueberries or raspberries. Banana is safe too but much more sugary. Our guinea pig vitamin C guide lists the best everyday sources, and what can guinea pigs eat and our guinea pig care guide cover the rest.
Strawberry questions
Can guinea pigs eat strawberry tops and leaves?
The welfare and vet sources we use cover the fruit, not the green tops or the plant's leaves, so we'd cut the top off and give just the red part. That way you know exactly what your guinea pig is getting. If yours has nibbled a green top, there is no need to worry.
Can guinea pigs eat strawberries every day?
No. Burgess and the PDSA both class fruit as a small treat because of its sugar, and VCA warns that too much fruit can upset the gut. Once or twice a week keeps strawberries special. For daily vitamin C, use bell pepper and leafy greens instead.
Can guinea pigs eat frozen strawberries?
Yes, once fully thawed to room temperature and patted dry. Frozen fruit straight from the freezer is hard and very cold. Thawed strawberries are soft and lose some vitamin C, but they are still a safe treat in the same small amounts.
Can guinea pigs eat strawberry yoghurt, jam or dried strawberries?
No. Yoghurt is dairy, which Burgess calls particularly dangerous for guinea pigs. Jam is mostly added sugar. Dried strawberries concentrate the sugar, and Woodgreen warns against mixes high in dried fruit. Only fresh strawberries are suitable.
