The best vegetables to give are the leafy green type, Kale, Spring greens, etc.
I find carrots are fine as long as they are given in small quantities.
Here is a list of some of the veg:
Cavelo Nero (type of Kale).
Bell Peppers (All)
Brussel Sprouts – not huge quantities as they are quite hard to digest.
The above is not an exhaustive list.
I only give my bunnies sprouts at Christmas. They are in the form of a sprout tree & it is a great boredom breaker as they have to work quite hard to get the sprouts. I only give them one tree between the six of them & it is put on rotation so that no one over indulges & becomes ill.
Fruit can be given, & boy do they enjoy it, but it must be given in moderation. Fruit is often high in sugar & starch. Given on a daily basis it could cause diarrhoea, gut problems & make them fat.
Apple pips contain cyanide but the quantity is very small & is encased by the seeds hard coating. This allows the pip to pass straight through the digestive system causing no harm. If the bunny chewed the seeds & the cyanide was released, it is such a small amount the bunny’s body can deal with it. For the cyanide to have any effect, the pips would have to be eaten in large quantities.
