I have a problem with an animation. I'm using the catnip mouse play animations to get a cat to hunt roaches and as you can see in the video attached, the animations are about a tile off from the actual roaches (ignore the roaches to the side; they were an extra lot).

It was suggested that I use this tutorial http://www.modthesims.info/showthread.php?t=242079 to reduce the number of tiles my object takes up, but when I come to the 'delete all the OBJD files except two', I only have one file (see attached pic).

Any help would be appreciated.

If you have a single OBJD then your object is only one tile, and you cannot reduce it more than that. You will most likely have to alter the CRES.

I need to move the cat closer, so how would I do that?
