I like the first one better than any of the monochromes shown. Maybe cropped a bit. In this color version, the fur on the body has texture and detail that was lost in the monochrome versions.
The second image is very nice, but the white stuff has to go and that cut around the ear is a job I would rather not take. In addition to getting a clean crop of the ear, you would then need to invent some background. Te bricks are OOF and you would need to match that degree and alignment of pattern etc.
The left white leg could simply be cropped out. But you need the ear.
The face of the second cat is better for me than the first.
