So can guinea pigs eat jackfruit and if somehow much can they eat?
Let’s start by checking out its nutritional data and find out a bit more about it.

A good amount of vitamin c is also beneficial.

As you can see it contains a fractional amount of phosphorus, calcium and fat but does contain a lot of sugar so do take care when feeding it to guinea pigs.
In terms of intake, once a month should suffice but dont feed it to them too often as guinea pigs cannot take the high sugar intake.
