You started the font as a symbol. That's why all right bearings are fixed. Not complicated to fix though, it is a 2 clicks job. Use auto metrics and set the left bearing at zero and the right bearing at 90.
If you want to further improve you can change the right bearing for the 'r' manually, I suggest somewhere in between 50 and 60 and add kerning for k and x with c, e, o and s.
Nice thingie, bit of cleaning in the horizontal and vertical lines and you're done.
Have fun and ... be nice to the cats
