In the warmer months, it's normal for your cat to try and drink water wherever they find it. If their water bowl is empty, they might try to get some liquid from other sources.

Poinsettia, a common but dangerous Christmas ornament, is one of the poisonous plants for cats. It's really important to make sure your cat has no access to this plant at all, since it seems that they have a natural attraction to poinsettias.
