Yup, carrots all the way here too. Rudolph usually gets a good few en route I think, as he only ever eats half of it here. Whereas Santa eats almost all of his cookie and drinks all his milk.
I know someone who reckons Reindeer love those big green outside leaves off the cauliflower - they always seem to be devoured in her house!
Our Scouts joined the annual "Big Beach Clean" over the weekend, and reminded us that bags take over 200 years to break down, but also that not only will some fish eat bags as they think they're jellyfish (and so die because they suffocate), the microbeads of plastics that break off end up moving up through the food chain and into the fish we eat as humans.
The same with glitter in reindeer food. It ends up in wild animals, and that can go through the food chain into the food we eat.
