Furry Writing, Worldbuilding, and Storytime

My science-fantasy world with intelligent animals living in harmony takes place millions of years after humanity mysteriously disappears from the Earth, I imagine how this goes is someone dug up some ancient human artifact that contained information about Christmas and felt determined to do something similar in their present day (wouldn't be the first time, a lot of their science and technology was borrowed from the humans when their ancestors dug up human ruins and deciphered human language). They might pull off a Santa and sleigh in the following ways:

1. Well all the humans are extinct from the planet and they haven't built Anthropocene Park yet, so best they can do is dress an overweight bonobo or other ape in red and strap a fake beard onto him. Or, if we're using animals that I actually have developed characters for and possibly the much cuter option, Santa Cat!

2. A sack of toys wouldn't be hard to come by, though they would likely have to be species specific since different animals like different things. Not a huge problem all things considered.

3. They have something called a Gravitational Slipstream Hovercraft which are nearly ubiquitous as the primary form of public transportation, think of them like aerial buses. GSS hovercrafts are probably by far the safest way to do this, as they can levitate and fly very fast under their own power, have active stabilization to keep itself steady as a sleigh needs an open top, have automatic collision warning and avoidance systems for both flying animals and other hovercraft, and can lift enough weight to carry a massive bag of toys. They would need to rent a hovercraft from one of the airlines/public transit providers, probably the Feline Ministry of Transportation as the Felines are more or less considered to have the best hovercraft tech. Unless Santa has a pilot certificate and is type rated on that hovercraft though, they would probably also need to "rent" a pilot too. From there, they can build a structure that resembles a sleigh around the hovercraft, which luckily wouldn't be hard to do since GSS hovercrafts don't have wings that need to be kept aerodynamically clear, nor do they have rotors or spinning engines that create airflow. GSS engines can still do their gravitational field manipulation from behind the sleigh facade.

4. They have actual reindeer, who are also sapient just like every other animal, and you could presumably just hire nine of them to pretend to run in front of your hovercraft. As for how they might levitate with the hovercraft while not having anything supporting their hooves, they can use a similar form of technology as a gravitational slipstream drive, albeit several stages more advanced and way more restricted by the government. A quantum interface can levitate pretty much anything within its area of effect. This would probably be the hardest part simply because they need to make a good case to the regulators why they should be allowed to use quantum interfaces in this way, and they would also need a government researcher to ride along with them and to be the actual one operating the quantum interface, possibly even my main character!

5. Rudolph is pretty easy, just strap a red light to her muzzle and pretend to bully her for a bit! The hovercraft has navigation instruments and would be flying in IFR so she doesn't actually need to shine through the fog.

Realistically, instead of delivering presents to individual houses, they would probably just parade around going from city to city and handing out free swag to kits/cubs/etc along the way. I doubt the government security agencies would give them access to their naughty lists so they'll just have to take their word for it on if they were naughty or nice. This world might have its share of Grinches too, mostly in the form of air traffic controllers freaking out and not allowing them to enter their airspace because their aircraft is "unsafe", such Christmas haters amirite?
