I haven't checked the thread to see what songs are listed, but Cindy Mangsen released an entire CD of cat songs in November, 2005 (long after this thread was started). Called Cat Tales: Songs of the Feline Persuasion, the CD includes both covers and new original songs. Perhaps the standout track is her original song Rudy's Big Adventure, the true story of the cat who got his head stuck in a garbage disposal and lived to meow about it. (It's a great song, but not easy to sing). Needless-to-say, husband Steve Gillette accompanies her on the album. And her own cat, Alice, graces the cover.

You can listen to clips of the songs here and find lyrics to the songs here
