Can rabbits eat Pineapple skin or spikey leaves?

A lot of fruits are edible to rabbits.

Pineapple & Papaya are suggested to feed,either fresh,in small amounts or unsugared dried pieces,as the Enzymes in these fruits help to break down the intestine blockages,such as wool block,which can be fatal. Rabbits also LOVE these foods.

Caution: Fruits,such as Plums,Peaches,Apricots & Nectarines,should have their Pits(stones,seed etc) removed before feeding to a rabbit as these Pits are POISONOUS to rabbits. The actual fruit skin & flesh is very nutritious to your bunny.

Never tried mine with Plums,Peaches,Apricots & Nectarines,

Mine love plum leaves as there is a tree near their compound. In the autumn they hang around underneath and eat them as they fall off!

i gave mine some peach a couple of days ago and they loved it - only a little bit for a treat.
