Using a Canon 60D with an 85mm Lens. Had my setting in "Manual" as follows:
"M" "1/8" "F10" "ISO 1600".
Well, 1/8th second is nowhere near fast enough for anything that may move, even a cat sitting still will be moving slightly and that is enough to blur the image with such a slow shutter speed. In addition, unless the camera is solidly locked onto a tripod or similar, then there is likely to be camera shake causing blur problems as well.
You used an f/1.8 lens but stopped it down to f/10. This is an ideal case for using a wide aperture to let more light in through the lens and getting a faster shuter speed to killl blur. Using f/1.8 would give you around 5 stops more light, allowing a shutter speed of 1/250th which would be plenty. In fact, if the cat was sitting fairly still, I would shoot at around f/2.8 to give a little more depth of field and still allow a shutter speed of around 1/100th. You would want to have the camera will braced though (resting with your elbows on the floor and keeping things steady should suffice) in order to kill any slight camera shake that could still be present.
As for what you are "not getting", you seem to be entering settings without any understanding of what they do or how they affect the image. Why did you choose f/10? You don't need that much depth of field. Why ISO 1600?, Why 1/8th? Other than you need to balance the f/10 to get correct exposure at the ISO you picked. Decide what aperture you NEED, what shutter speed you NEED, then set the ISO required to allow those settings and give correct exposure. Those settings you used in that shot seem to have been picked at random, with no thought as to how they will affect the result.
