I don't have a cat (or a workplace), but cat cafes seem to be purring right along.
Digging a bit, it seems that one in seven kids has cat allergies, which is twice as much as the rate with kids and dogs. Either way, that's a fair number of people, so if there's any sort of discrimination involved, I'm sure cat lawyers will pounce.
2/5 would not bring cat to work again. Also, the building has since put down rat-poison to sort out a rodent problem, so it probably wouldn't be safe for him, sadly.
If you _really_ want to work with your cat, may I suggest remote working from home as the way to go?

The apps are also not "mass produced", they have really nice animations and you can definitely feel that there has been a lot of effort put into them.
They also make some music player and encryption apps so they're not all cleaning apps.
Don't get me wrong, I love animals and I have my own. But where do we draw the line between personal and professional? How do we tell John that his dog is OK, but Bob that his dog needs to stay home?
Cat-related allergies are much more common than dog ones. Generally dogs are also better trained than cats and behave more predictably.
