Any recommendation for a CD changer?

Looks like your cats do prefer a single unit instead of digital separates

This one caught my attention as I love changer convenience as well.

Just stop.  Stop with the CD changer that’s like 30 years old technology.  Just get something like this, load all your CDs into it and be done with it.  And if it gets you into streaming eventually so much the better.

I am not understanding.  Your cats chewed an optical cable.  Can’t you just get a new toslink cable?

It's not toslink nor coax. It's Stan Warren's proprietary digital cable. With the 2.1mm micro jack ...with two wires connected to Led light. Can't find that part, otherwise I'd solder it myself. 

Onkyo is the only brand (that I am aware of) that still makes a CD changer.

If you want to shop used, you can pick up a Sony ES changer off Ebay for dirt cheap. They're pretty much bulletproof.
