Can Rabbits Eat Spinach? What You Need to Know

Spinach is often hailed as a nutrient-packed green for humans, but when it comes to rabbits, things aren’t quite so simple.

Can rabbits eat spinach? Yes — but in small amounts and not every day.

Is Spinach Safe for Rabbits?

Spinach is safe in moderation, but it contains a high amount of oxalic acid (also known as oxalates), which can build up in a rabbit’s system over time and potentially lead to health issues like kidney problems or bladder sludge.

That’s why it should be offered only occasionally and always as part of a varied diet.

Nutritional Benefits of Spinach

Spinach is rich in:

Vitamin A, C, and K
Iron and magnesium
Antioxidants

These nutrients can support your rabbit’s immune system and overall health — but only when fed alongside other low-oxalate greens.

How Often Can Rabbits Have Spinach?

We recommend feeding spinach no more than once per week. For an average-sized adult rabbit, a small handful of fresh spinach leaves is plenty.

Mix it with other rabbit-safe greens like spring greens, basil, or coriander to reduce oxalate load and support a healthy gut.

Which Parts of Spinach Are Safe?

Leaves: Yes — fresh, raw, and thoroughly washed.
Stems: Yes, but only in small quantities (they’re tougher to digest).
Cooked Spinach: No. Always serve raw to preserve nutrients and fibre.

When to Avoid Spinach

Avoid feeding spinach if your rabbit is:

Already prone to urinary issues
On a high-calcium diet (too many oxalates + calcium = risk of bladder stones)
Under 12 weeks old (stick to hay and starter-safe greens)

Serving Suggestions

Wash leaves well before serving.
Tear into smaller pieces for easy nibbling.
Mix with lower-oxalate greens to balance the meal.
Avoid feeding spinach several days in a row.

Conclusion

Spinach can be a healthy leafy treat for your rabbit when served sparingly. Thanks to its oxalate content, moderation and variety are key.
