Lettuce and leafy greens
Risky — depends on amount or preparation
Dogs: Safe · Cats: Safe · Rabbits: Risky · Birds: Safe
By animal
| Animal | Verdict | Why |
|---|---|---|
| Dogs | Safe | Harmless, mostly water, of no particular benefit. |
| Cats | Safe | Harmless. |
| Rabbits | Risky | Dark leafy varieties are good. Iceberg specifically is not. |
| Birds | Safe | Dark leaves are a good staple green. |
What it actually does
For a rabbit the type matters and the difference is real: romaine, cos and other dark leaves are nutritious, while iceberg is mostly water, offers almost nothing, and contains lactucarium, which in quantity is sedative and can cause diarrhoea. Spinach and kale are fine in rotation but high in oxalates and calcium respectively, which matters for rabbits prone to bladder sludge.
No reliable dose threshold has been published for this. Anything presenting a specific safe amount is extrapolating.
Body weight decides almost everything here, so what is trivial for a 40 kg dog can matter for a 4 kg one, and a bird is smaller again. Where a real published threshold exists this page gives it; where none does, it says so rather than inventing one.
