Good, genuine real kitteh nodes I have live, based on the new patched kitteh wallet code, which will be updated soon are:
193.227.134.111:22566
62.151.183.106:22566
You will see all sorts of strange nodes appearing in your kitteh wallets, with odd ports and client names - these are rogues to the best of our knowledge, and will attempt to cause sync issues with the main network. The team is on it, and will patch the wallet asap, and release new clients. You can clone the github repo if you know how, and build a fresh wallet from there.
I'll keep you posted as best I can.
