Kiwifruit

A small piece works as an occasional treat with a little vitamin C and water.

One small cube (about 1 cm) per serving, and never at the expense of the main diet.

Peel and dice small with no seasoning.

Cats need no fruit; check for redness or drooling around the mouth after the first taste, since actinidin can irritate it, and keep treats within about 10% of daily energy intake.

A source of vitamin C, dietary fibre and potassium, with soft flesh that is easy to cut into small pieces.

1-2 small pieces (about a tablespoon) for a small dog, within about 10% of daily energy intake.

Wash, peel and dice into bite-sized pieces; no sugar, honey or yoghurt dips, and dried kiwi is too sugar-concentrated.

The enzyme actinidin can irritate the skin around the mouth and the gut, so sensitive pets get only a tiny amount while you watch; kiwi is moderately sugary, so skip it for diabetic or overweight dogs.
