are christmas trees poisonous for cats

No, Christmas trees are not poisonous for cats. However, it's important to keep the tree in a safe location to prevent your cat from climbing it and possibly knocking it over. If you have a live tree, make sure you water it regularly so it doesn't dry out and become a fire hazard. Also, avoid using any ornaments or lights that could pose a choking or electrocution hazard for your cat.
