I have never resolved the problem, but have found a way that works for a period of time. I got a large dog crate. It's big enough to hold a litter box, a large cushion for him to sleep on, and bowls of food and water. When he acts out against one of my cats, I put him in the crate for a time out. At first I just left him in it for half a day. That didn't really help. I found that it's most helpful to leave him in the crate for at least 24 hours, and at times for longer, depending on how bad his behavior was on that particular occasion. The crate is in my basement which is below grade, so it's always in the 60s there. The isolation is what seems to be the key to this working. When I crate him, I don't go down to the basement except once or twice to clean the litter box. And when I do that, I make sure he understands that I am very angry with him by speaking harshly to him and telling him how bad he is. When he's out and starts to act out, I yell CRATE at him so that he begins to understand what's coming if he doesn't stop the behavior. I have left him crated for as long as two days. But when he comes out of the crate, his behavior changes for, sometimes weeks at a time. And I constantly praise and pet him when he starts his aggressive behavior and when yelling CRATE immediately stops it. Good luck, this has been ongoing for 5 years now, but this method has drastically improved things.

Sam, I forget the name of your kind, so I went to check. Your kind is probably Xinkou (Chinese simplified 馨å£)ãÂÂYour cultivar is considered even more expensive than these no color type. Mine is called Suxin (Chinese Simplifiedç´ å¿Â) meaning "pristine at heart". Your pictures were two years ago. How about this year? Are they still alive?

Yahoo Messenger seems to be retrenching/cutting back and who knows, it could be soon closed as the company restructures and/or gets sold in pieces. It's not a lively part of the site. It might be a good time for you and your correspondents to consider shifting to a more modern and vibrant platform, like WhatsApp. Now owned by Facebook, it has many hundreds of millions of active users. No advertising.

Do you actually USE Yahoo Messenger? If yes, I would uninstall whatever YM you have now and then make sure that you download and install the latest version directly from Yahoo. If no, then uninstall YM and forget about it. In any case, I would not do anything that a popup tells me to do. YMMV.
