Hello! I posted the other day about a stray/near feral cat that I have taken in with the aim to rehabilitate and keep myself. Over the past 2 days he's been extremely frustrated, scratching on walls and doors and howling through the night. I'm a bit worried my neighbours will hear and be irritated by him, as he really don't stop for long. He was getting on great with my other cat Otis, but yesterday attacked him out of nowhere. I'm still trying to get him neutered and am waiting a call back from the vets. He currently has everything he needs and a feliway. I go in there a few times a day and just sit with him but he hides and only comes out when Otis is in the room, which I'm not allowing at the moment due to his previous attack. I'm feeling at a bit of a loss and we're all just stressed out and wondering what I can do to help him to settle? Should the neutering help? I'm trying to get him done as soon as I can.
