Chances are your cat will try to climb all over it sooner or later. If you have a live tree, never let your cat drink from the water in which it stands . Even if you use pet safe preservatives, the tree itself releases toxic sap into the water, so you'd better cover the water altogether and make it inaccessible to pets. Avoid using tinsel, strings and hooks as part of your tree decorations . All are extremely dangerous to cats if swallowed.
Fragile ornaments can be dangerous.
Glass shreds on the carpet are a safety hazard to humans as well as felines - so keep all breakable ornaments out of your cat's reach. Holly, mistletoe, poinsettias, ivy and Christmas roses, as well as the Christmas tree itself are all poisonous. Try not to use them or to keep them well out of reach. Spray the lower branches of the tree with anti-chew plant spray. Christmas can be very stressful for some cats - All the changes in the decoration, having guests over or simply changing the familiar routine can be very stressful for your cat.
