Yes, degus can eat a little lettuce. Romaine (cos) and dark green or red leaf lettuce are the best kinds, given as a few thumbnail-sized pieces once or twice a week alongside other vegetables. Skip iceberg and pale lettuce, which are mostly water. Too much lettuce at once can bloat a degu, so keep the portion small.
| Safe? | Yes, in small amounts |
| How much | 2 or 3 thumbnail-sized pieces per degu |
| How often | Once or twice a week, mixed with other veg |
| Best served | Romaine or dark leaf lettuce, washed and dried |
| Watch out for | Bloating, soft droppings, iceberg lettuce |
Is lettuce safe for degus?
Yes, the leafy kinds are. Degus are strict plant-eaters, and hay should make up most of what they eat. Fresh vegetables are a small extra on top. Degutopia lists lettuce among the vegetables degus can have weekly, and PetMD names romaine and green or red leaf lettuce as safe vegetables for degus.
Not every source agrees. Burgess's seasonal food guide, which groups degus with chinchillas, puts lettuce on its avoid list because both species have very sensitive guts. Degutopia also warns that overfeeding fresh greens, "in particular lettuce", can cause bloating. We follow the middle path: a little dark lettuce is fine for a healthy adult degu, but it should never be a big pile or a daily staple.
How much lettuce can a degu have?
Two or three pieces about the size of your thumbnail, roughly 1.5 cm (half an inch) across, is enough for one degu in a single veg session. PDSA advises a small portion of fresh greens and vegetables only once or twice a week, and Degutopia says the same. Mix the lettuce with one or two other vegetables rather than giving lettuce alone, and change what you offer each week.
Which lettuce is best for degus?
| Type | Verdict | Why |
|---|---|---|
| Romaine (cos) | Best choice | Darker leaves, more fibre, named as safe by PetMD |
| Green or red leaf lettuce | Fine | Also on PetMD's safe list |
| Little Gem | Fine in small amounts | A small romaine type; use the darker outer leaves |
| Iceberg and pale lettuce | Skip | Mostly water, little goodness, can loosen droppings |
| Bagged salad mixes | Check first | Pick plain leaves only, no dressing, onion or garlic |
How to give lettuce to a degu
- Wash it well. Degutopia advises washing shop-bought veg thoroughly to remove chemicals, then shake or pat it dry.
- Tear it small. Tear two or three thumbnail-sized pieces per degu.
- Give each degu its own share. Split the veg between bowls so you can see who ate what.
- Clear leftovers. Remove uneaten leaves after a few hours before they wilt or go off.
If your degus have never had lettuce, start with a single piece and wait a day. Soft droppings mean it is too much for that degu.
What to give instead of lettuce
For variety, rotate lettuce with a floret of broccoli, a slice of cucumber or a little carrot top (our carrot page explains why the leaves beat the root). Our safe food list for degus and degu diet guide cover the full weekly plan, and the complete degu care guide covers everything else.
Lettuce questions
Can degus eat iceberg lettuce?
We'd leave it out. Iceberg and other pale lettuces are mostly water with little goodness, and Burgess notes iceberg contains lactucarium, which can be harmful to rabbits in large amounts. Degus have similarly delicate guts, so romaine or a dark leaf lettuce is the better choice when you do give lettuce.
Can baby degus eat lettuce?
Wait until young degus are fully weaned and settled on hay and nuggets, then add greens one at a time in tiny amounts. PDSA and the RSPCA both say to introduce new foods slowly to avoid stomach upsets. A single thumbnail-sized piece is plenty for a first try.
Why did my degu get bloated after eating lettuce?
Degutopia warns that too many fresh greens, lettuce in particular, can cause bloating. A degu with a swollen, tight belly that is hunched or not eating needs a vet the same day, because bloat can become serious quickly. Next time, give much less and mix it with other vegetables.
Is lettuce good for degus with diabetes?
Lettuce is low in sugar, so a little romaine is one of the safer fresh foods for a diabetic degu. Keep to the same small portion once or twice a week and check with your vet, who may want to manage the whole diet closely.
