Cultivated Trees and Plants Potentially Poisonous to Animals

The following commonly available trees, shrubs and plants are often sold through plant nurseries, and pose a potential hazard to animals if they are planted in or around animal enclosures. If these plants are found to be desirable for landscaping purposes, it is important to position the plants well away from where animals can reach them. Furthermore it is essential to always provide a balanced nutritious diet to animals at all times so that they are not driven through hunger to eating unusual plant material. It is also important to remember that the careless disposal of tree and plant prunnings into an animal enclosure is a frequent cause of poisoning.
