It sounds like Wurp is majorly territorial. I wonder if Shortstack's presence in the den took him by surprise - especially if Wurp is used to having that room all to himself. This is certainly proving to be a tricky introduction, and I have to say that you're handling it all really well so far. The eating out of the same bowl is HUGE progress Don't minimise it. I think you're essentially learning that Wurp needs to progress in extra-baby steps right now. Being deaf, knowing his territory, and who to expect where and when, may well be even more important to Wurp than it is to the average cat.
Carry on with the joint feeds for now - they're clearly going really well :bigthumb: - but don't allow them to get into a situation where Shortstack is settled and Wurp enters. Always be sure that Wurp SEES Shortstack enter the room, and always be sure that Shortstack goes in AFTER Wurp. This should help retain Wurp's authority in his own eyes, and help him feel more secure and settled about Shortstack's presence.
Also, get a load of blankets, cardboard scratchers etc and let Shortstack use them for a few days to get them thoroughly soaked in his scent. Then, scatter them strategically about the house, making sure they're somewhere that Wurp won't be taken by surprise. Do one room at a time, and take it slow so that Wurp isn't overwhelmed. Hopefully, this will help Wurp adjust to sharing territory peacefully with Shortstack. He basically seems alike a cat who really struggles with changes in routine, and needs plenty of warning to get used to the idea.
Hang in there. This WILL work out. Warp just needs extra time to process everything :catguy:
