Making your Christmas animal-friendly takes a bit of extra planning. (But it is worth it!) Please keep in mind your pets, animals being exploited by industry, and wildlife.
Companion Animals: Make sure that any plants hanging around your house are non-toxic, and put the toxic ones in rooms where the animals do not enter, as the leaves can fall onto the ground even when they are out of reach! (Thanks for the tip, A.M.!) For example, mistletoe is toxic, as are holly and poinsettia-- unknowing animals might taste these plants and fall ill, so be careful! If your cat likes eating tinsel and ribbons, you should do without these frills. (Never give an animal as a gift. Having a companion animal requires a lot of effort and money, and people should only adopt once they are sure that they can handle it.) I also suggest giving your pets new toys and lots of love this Christmas-- share the joy!
Industry animals: Here I am talking about animals raised for food, fur, wool, and leather. Please take care to give cruelty-free gifts to your loved ones! And how about serving a vegetarian turkey this year? The brand Tofurkey is popular, and there are many other kinds of fake meats in regular grocery stores as well as health-food stores. Get in touch with any party organizers early to make suggestions.
Wildlife: Seeing that wild animals live in nature, it is very important to keep their home intact! Try to minimize your environmental impact on Christmas by wrapping presents in scarves and reusable gift bags, avoiding ribbons and gift-wrapping paper. Use a live tree in a pot this Christmas, which you can keep inside for a few years and plant in the springtime!
