Oranges

Animal Safety: Dogs: Yes Cats: No Rabbits: Yes

Free Grazing: No
Although oranges are safe for dogs and rabbits, the pips peel and pith must be removed first.

Lifespan: An orange tree in the UK can live for 50 years or more. Oranges tend not to be able to survive the harsh UK winter and need to be moved into greenhouses or indoors during the winter months. As orange trees are grown in containers in the UK their size is restricted. Although 1 to 3 metres (3-10ft) is quite common. There are over 600 varieties of oranges around the world.

Sew: Growing orange trees from seed can take 5 to 15 years to fruit. It is more common to buy a ready grown tree.

Harvest: Orange trees in the UK usually fruit in the late autumn and winter months. The fruit develops around a year from flowering. They start ripening from around November through to spring, depending on the variety, warmth, and sunlight they receive in conservatories or greenhouses.

History:
Oranges originated in Southeast Asia (China/Himalayan foothills) over 20 million years ago, with them first being mentioned in Chinese literature by 314 BC.
They were fist quite bitter and those bitter varieties arrived in the UK around the 13th to 14th century. The sweeter varieties arrived in the UK around the 15th to 16th century.  

Eating:
Oranges offer fibre, potassium, and vitamin C

Dogs can eat oranges in moderation as a healthy treat, but only small amounts due to the sugar content.

Cats should not eat oranges or other citrus fruits because they contain essential oils (limonene, linalool) and psoralens that are toxic, causing digestive upset, skin irritation, and potential central nervous system issues.

Adult rabbits can eat a very small piece of orange as an occasional treat, but it's generally not recommended as a regular food due to its high sugar and acid content, which can upset their sensitive digestive systems.
