Pine cones must be watched closely when being baked in the oven in case there is smoke or fire. It is unknown whether sap from trees is toxic to rabbits or not, so it is better to be safe and remove all sap prior to giving the pine cones to your rabbit. Do not use bleach on pine cones to remove sap and bugs. It is toxic to rabbits.

Mental stimulation is important for the happiness and well-being of your pet rabbit. Your rabbit should always have toys available to play with, as rabbits that do not get proper mental stimulation often resort to destructive behaviours to pass the time. There are many toys available at pet stores for rabbits, although for a more cost effective toy you can look to the outdoors. Pine cones are ideal for rabbits that love to chew, and can result in hours of fun. It is important that they be prepared and dried before giving them to rabbits in order for them to be safe for chewing.
