Oyster Mushroom

Pleurotus ostreatus
Also known as:oyster mushrooms
CatSafe

Cats need no mushrooms, so a little cooked chopped oyster mushroom is at most a tiny novel treat with almost no calories.

Feeding advice:Only a very small piece now and then, never in place of the main diet, and still within about 10% of daily energy intake.
Preparation:Trim, rinse, chop very small and **cook thoroughly**, with no salt, oil, garlic butter or sauce.
DogSafe

Oyster mushrooms are low in fat and supply dietary fibre and B vitamins, and once cooked and sliced they are a mild, occasional treat.

Feeding advice:Feed only a small amount within the daily treat allowance and within about 10% of daily energy intake, with complete dog food as the main diet.
Preparation:Trim and rinse them, tear or slice into small pieces, then **cook them through** by steaming or boiling, with no oil, salt, garlic butter, soy sauce or other seasoning.

Notes

**Never give a cat wild mushrooms** - one bite can cause serious poisoning; cultivated ones need cooking too, as raw mushrooms are harder to digest and may carry bacteria; most cats ignore them, so **contact a vet immediately** for drooling or vomiting.
