Will this be dangerous for my house cat?

Not sure but would have thought it would be fine it’s certainly less toxic than other similar products I have used

Can this be sprayed onto carpet and upholstery?

I've not needed to spray upholstery and my floors are hardwood and tiled. I have though sprayed rugs without any ill effects or stains. This spray is completely odourless and clear. I find it most effective on tiled floors. At the start I was spraying certain areas twice weekly (bathroom/kitchen/utility) but now I find that it is effective for about a week or a little more between sprays. You don't need to saturate areas with the stuff - a light misting will do fine. A 500ml bottle lasts me about 6 weeks (I found 5 Litre ones much cheaper and got that after the first 500ml one) When I started using the spray I was finding dead ones about 3 each day now I'm getting only 2 in a month! If you know where they are coming from then you can stop them completely. I live in a block of flats where they could be coming from beside above or below me so I don't know the source. Rest assured that this spray works great and you're not wasting your money - but be patient.
