More little logistical conveniences in a world with corporeal daemons:
Bathrooms usually have a bed and/or a perch to give daemons a comfortable place to rest while their human bathes or showers other than the bath mat. Some daemons are happy to join their human in the bath/shower, but many don’t like getting wet or have forms that would make it difficult / possibly dangerous (e.g. a lot of rodents), and even for those that like water soaked fur can take a long time to fully dry so bathing isn’t usually an everyday thing.
Daemons don’t normally wear clothing, but there are times when it’s necessary or at least much more comfortable - for the same reasons animals sometimes wear clothing in our world. Not all fur and feathers are created equal, and a fennec fox, or a chihuahua, or a serval, or a parrot wouldn’t have a good time in cold climates. Children’s daemons can just turn into arctic animals and/or crawl into their human’s clothing (as shown in The Golden Compass), but daemons with warm-weather settled forms are out of luck, and often wear sweaters, hoodies, and/or earwarmers. Superheated pavement in warm climates, and road salt in cold ones, can also hurt a daemon’s feet just like a real animal’s, so many wear protective paw booties.
Human clothing made to accommodate daemons is also common. The most obvious is arm and shoulder pads which allow large birds - especially birds of prey - to land and ride on their humans’ arms or shoulders without injuring them. People don’t really wear falconry gauntlets because it’s not like they’re just putting them on for a hunting or training session with a bird, it’s daily life including times when you need to use both your hands for something else. Clothing may also have special pockets for very small daemons to ride in, sometimes incorporating clear plastic windows. Daemons that are too big for a pocket but small enough that walking around in crowded places is awkward - e.g. rats, ferrets, rabbits - most commonly ride on their humans’ shoulders, but sometimes being carried in a sling is easier, more comfortable, and warmer.
Doors with round handles are rare. Daemons don’t go far from their humans so it’s not incredibly limiting or dangerous to not be able to open a door, but it can be annoying and inconvenient to not be able to, especially when the human’s arms are both full of dishes or grocery bags or something. You’ll sometimes see ladders or rough surfaces attached to doors so small-ish forms can climb them, although this is probably seen as tacky.
Tailoring is an integral part of society as daemon-related changes to clothing are extremely common.
It is very common for tailors to have a primate daemon as this allows the human tailor to measure the human while the primate measures the daemon. There are also daemon weight scales in all tailors to ensure that specialised pockets etc are made secure and strong enough without a one-size-fits-all approach that could lead to unnecessary bulk, while also embedding it in the clothes in such a way that it does not strain the rest of the fabric in an unseemly way.
It is just a universal fact of architecture that all buildings are designed with perches of some kind dotted around a little over head height, particularly in seating and dining rooms. Styles have varied throughout the years, from stylised carved poles of stone or wood either coming straight out of the walls, to coming out a little and then running parallel for a more integrated look, to shelves or wide picture rails, and many more. You can use the style of perches to guess the age of a building.
Daemon beds are a popular business. Some are designed to integrate or clip on to an existing bed for those with small daemons but feel that sleeping cuddling your daemon is childish, or for those that share their bed and worry about a partner touching or crushing them accidentally in the night. Some are designed for a natural feel that that daemon’s normal counterpart would desire, others are not dissimilar to a smaller or lower version of a human bed, and most retail beds are offered with a custom built daemon matching set. A lot of people with more easy going type daemons just settle for a blanket or cushions on the floor or on their person’s bed.
I have a couple additional thoughts:
Light rail/ trains remain more popular and important for travel in this universe. Cars are still common but they had difficulty becoming the default mode of transportation as they needed to be larger, have more seats, and have special belts/harnesses/other safety features for daemons which made them more expensive and took longer to modernize
The first floor of public buildings is required to be large and spacious enough, and with a big enough entrance, to accommodate large daemons
Hospitals, apartments, and hotels are all required to have a couple of large rooms to accommodate those with very large daemons (as with ADA compliance in our world, how well these requirements are met varies)
A common public accessibility tool are large wagons that can be used by people with large but slow moving daemons such as big tortoises. Your tortoise daemon goes in the wagon, and now you can pull the wagon and keep up with your friends. Wheeled fish tanks for aquatic daemons are also available (I’d like there to be a handless design, like something that attaches to a belt so you can pull your daemon around and use both your hands but I’m having trouble envisioning a design that isn’t super cumbersome or a fall hazard)
And a couple in-universe personal thoughts on the above:
Avec has bad weather booties for his feet. He does not like them. But also does not like stepping on icy or boiling sidewalks so sacrifices must be made. He also wears a satchel to help me carry my stuff (very convenient)
Avec does NOT have his own bed. We can share just fine. My parents offered to get him his own bed when he settled and we refused
