Oh god, the Winston situation is still pissing me off big times. I think it was then I started to REALLY dislike her (haven't been watching that long before). Even her hardcore fans in the comments were saying she's not right, but she was all "This is MY life and I know MY cat, so I clearly know how to act the best". God, woman, he was around for a week. What do you mean you did everything you could and it wasn't working between them?! Open
bleeping google and all the searchings on the topic will be advising you to keep the new cat in one room and let your old cat go around everything else (because it's there safe place and they don't need to feel threatened) and get familiar with the scent of other cat from the door. And that's just the first step and the whole process is going for like 3 weeks, to make sure all the animals are comfortable. Of course there are exceptions, but it definitely applies to someone like Lumi. But surely Lyds knows best and not any professional should be listened to
