So, I have a world not unlike Zootopia, i.e. populated with all sorts of anthropomorphic mammals.
There's a scene in my story where a wolf-person and a cat-person are looking at chew toys in a pet store (there are also non-sapient, non-anthropomorphic animals in this world, some of which are domesticated just as in our world)... and I found myself suddenly wondering about a few things.
People in this setting still resemble their animal counterparts; dog-people like to gnaw on bones, cat-people are fascinated by laser pointers, etc. That being the case...
- Would dog-people want to have purpose-made chew toys? Or would they have some other outlet for these urges? (Wild wolves get along without, so they don't seem necessary. Sticks are practically free, towels¹ are convenient, or there's the bone from last night's dinner.)
- Would many other animals (e.g. raccoons, goats, etc.) want such things? (Let's ignore rodents that need things to gnaw on to keep their teeth from overgrowing; they're a slightly different market.)
Basically, I'm trying to figure out how big this market would be. (That it would exist seems to be a given; after all, some humans need chew toys², and, well, there are niche markets for all sorts of weird things. However, there's a big range between 'obscure online sellers' and 'every gas station and convenience store'.)
(¹ There's also some magic in this setting which is mostly not relevant except that one of its properties is the ability to prevent or at least significantly mitigate damage from chewing on non-food items, such that using soft things like towels would be plausible without them being almost immediately destroyed.)
