As you can see lychees contain a hint of calcium, phosphorus, fat and fibre, quite a bit of acidic content but a lot of sugar.
This means that rabbits can eat lychees but only one a week due to their sugar content. It contains too much sugar for rabbits to eat too much of them. However they will enjoy them.
