You went about introducing Henry and Cubby all wrong. If you want them to get along, listen to the advice you're given. I'd hate to see another cat wind up at a kill shelter simply because their owners didn't do their research. I'm sorry I'm being a little harsh, but I get SO tired of people not listening.
Put Henry in a room by himself with his food and water and litterbox. Take a towel and rub Henry down. Take another towl and rub Cubby down. Allow the cats to smell each other's towels. After a COUPLE OF WEEKS (not hours), stack baby gates in the doorway of the room where Henry is. This will give them a chance to get acquainted and be protected at the same time. After ANOTHER COUPLE OF WEEKS, allow Henry out of the room to explore, standing by with a squirt bottle filled with water.
Hissing and growling is normal behavior. Unless there is SERIOUS fur flying or bloodshed, let them be, just supervising them. Do not allow Henry to roam free unless you are home. (at least for a while). You'll also need to add a litterbox (one per cat, that's the rule). This way there won't be any potty issues.
Please follow these instructions. Remember, introductions don't happen overnight. It takes alot of patience and love.
