  1. Hi. Are you familiar with “java apples”? We have a tree in our yard and I was wondering if the fruit and leaves are safe for guinea pigs, but I can’t find any answer for it. I’m wondering if maybe you could help me out.

  2. Hi Aika,

    Java apples are not actually apples, they are a fruit called Syzygium samarangense (thanks Wikipedia!) Unfortunately I couldn’t find anything either that says it’s okay to feed them to your cavie so I would play it safe and not give them any.
