Can Rats Eat Pak Choi?

Updated November 2026.

Yes, rats can have a little plain pak choi as part of their fresh-food allowance. RSPCA Australia explicitly includes bok choy and other Asian greens in its rat guidance.

Is bok choy the same food as pak choi?

In this feeding context, pak choi and bok choy refer to the same familiar Asian leafy vegetable. RSPCA Australia names bok choy among appropriate dark greens and non-starchy vegetables. The UK RSPCA gives a broader small-amounts-of-vegetables rule rather than a pak-choi-specific serving chart. That combination supports offering it as variety, not making it the main meal. RSPCA Australia: What should I feed my rats?

Leaves, stems, raw or cooked?

The leaves and pale stems have different textures, so make the offered piece easy for your own rat to handle. Separate the leaves before rinsing because the crowded base can hold grit. Plain steaming is an option, followed by cooling; a portion lifted from a salty stir-fry is not equivalent. We do not have a source-supported stem-to-leaf ratio or a prescribed chopping size.

What does the nutrition entry actually cover?

The CoFID entry below is for steamed pak choi, not raw leaves. This matters: its figures cannot honestly be labelled as the raw vegetable’s composition. Its low fat and high water content describe a useful bit of fresh variety, not a complete rat diet. Do not turn a nutrient table intended to describe human foods into an instruction to feed a rat a large bowl of greens.

Does pak choi need to be banned as a brassica?

A blanket ban on all brassicas would conflict with the welfare guidance that explicitly includes bok choy. Equally, that guidance does not say unlimited amounts are suitable. Introduce a small taste without simultaneously changing several other foods. If loose droppings or poor appetite follow, stop the new addition and ask your exotics vet if the problem persists. If a rat already ate plain pak choi and seems normal, there is no reason from these sources alone to assume poisoning.

The food facts, not a rat serving size

These are values per 100 g of the named food, from Public Health England: CoFID 2021, table 1.3 Proximates. They describe the food, not an amount to feed a rat. Preparation and variety matter; these are reference values, not a measurement of your particular portion.

Keep the whole ration in view

RSPCA: What to feed pet rats recommends rat-specific food as the staple, with suitable fresh variety inside the normal allowance. An appealing snack is not evidence of a balanced meal. For the wider picture, use our rat diet and nutrition guide, check another ingredient in the rat food checker, or start at the Pet rat care hub.

Make the usual food interesting

Fresh treats do not need to carry all the entertainment. Our Mushroom Rat Foraging Cups are a pair of cage-mounted cups for small dry treats, dried herbs or scatter feed. Use them for the usual suitable dry ration rather than wet fruit, sticky sweets or foods marked avoid here. Check fittings and remove damaged cups, following the product care instructions.
