Hello,
I'm coming to you for help because I'm in a bit of a tricky situation and I genuinely don't know what to do.
I have two domestic shorthair cats — the first, Misty, whom I took in back in October 2011, and the second, Happy, whom I took in in September 2012. I rescued them both at around two and a half months old, so they're now just over 8 and 7 years old respectively.
When Happy first arrived, even though she was tiny, that didn't stop Misty from trying to assert her dominance — to the point where they had a proper scrap (I obviously stepped in to stop it getting nasty). Over time, they eventually got on fine, and up until recently things were going quite well (they sleep together, groom each other, etc.).
There was a period a while back when things weren't great between them, and we later found out it was because Misty had ear mites, which was making her irritable and aggressive, so she kept going for Happy. We got her treated, and at the same time had them both spayed (as the seasons were an absolute nightmare — constant yowling and spraying everywhere). After that, things settled down again.
However, recently (about two weeks ago), they had a big fight one evening for no apparent reason, and I had to step in to break it up. I separated them, and a few hours later they were able to be near each other again without too much bother. But then last night, it happened again — and this time it doesn't seem quite so straightforward: Misty spent the night with me in my room, and Happy with my mum in hers. In the morning, I tried reintroducing them, but Misty was having none of it and immediately turned aggressive. I told myself I'd try again later. At lunchtime, I tried once more, and it was even worse — Misty went straight for her, Happy got wound up too, and it turned into a really vicious fight, with Misty even wetting herself in the process. I stepped in and separated them again (getting scratched for my trouble).
So that's where things stand — Misty is in my room (with a bowl of dry food and a water bowl), and Happy has the run of the rest of the flat, yowling her head off the moment she's left on her own (my mum was out all afternoon, and I can tell you my nerves were well and truly frayed).
I honestly don't know what to do. I don't want to let them fight and have it end badly, but I also don't want to keep them separated because it very quickly becomes unbearable.
Thanks in advance for reading this and for any help you can offer.
