I've had plenty of Good Coondogs that couldn't catch Cats. One time I had Three Coon dogs That I was trying to start a Cat which crossed the road in front of me. I Left One dog in the box, because she was chasing Elk all night and I was still pissed at her!
For 45 Minutes I tried to start that cat track with 3 "coon" dogs.. Finally after 45 minutes I went and Let the "elk Chaser" out of the box.. She went up there with all the other dogs just the same, Made a Circle and opened up and Moved the track out, Jumped it, and had it caught 20 minutes later.. And made it look effortless.
If Catching a Coon was qualification for catching a Cat, I'd be catching a hell of a lot more cats..
