As the title says, the cat won't stand. It goes to rest and calibrate mode. But the servos don't go to stand position. When I run the ktr command the cat walks on its knees instead of being in the stand position. Anyone knows how to fix this?

After a few more tests I believe yo are correct. I changed the calibrations back to zeros. And I noticed that while holding the cat in the air it does go into stand position but when i put it on the ground the servos seem to give out.
Yes, the calibration value should be >-9 and <9. Otherwise, you may have a reduced range of reachable angles. You can read the forum post "the logic behind calibration" to better understand the process.
I also notice that you have a plastic frame. Is that a DIY version? The servos may be too weak for walking purposes.
Do you have a video showing the behavior? And pictures showing the wiring of the joints.
