Hi all, I'm new here, but I've been scouring the net trying to figure out a solution to my problem and I thought it wouldn't hurt to try here.
I have two Korats, from the same litter that just turned 3 years old a few months back. Also a few months back, one of them started to get rashes up around her ears and dry patches on her skin.
Back in August, we took them both in because Jasmine (the one with the rash) had her rash got worse and we got worried. That trip went fine, we adjusted some of their foods and litter after as they thought it might be a skin allergy. Jasmine got her self an allergy shot to get over the rash.
Fast forward to the last week of October, Jasmine has what appears to be another allergic reaction to something and her eye swells up. It's late at night, so we're off to a 24 hour vet, and I don't take her sister Mila with her this time on that vet's recommendation. Well, big mistake. When I brought Jasmine home that night her Mila acted like she didn't even know her and was hissing and growling at her. This went on for two days with me keeping them separated and after 2-3 days we got them in the room again and they appeared to love each other again.
It should be said that prior to that trip to the vet, you wouldn't find two cats that loved each other more. They went everywhere together in the house, slept together constantly, grooming each other, inseparable. We had gotten them back to this state, which was a giant relief.
Fast forward again to last Friday, and now they are due for their annual vet checkup. After an ordeal getting Jasmine into the carrier that involved nervous peeing on the floor we finally got them in the car and off we go to the vet. Our vet does a couple of skin tests on Jasmine to see if her allergy problem is not an allergy problem (tests were negative), and they both get their yearly rabies vaccine (Purevax).
We come home and everything seems to be okay, at least this time they shared the traumatic experience so we thought they'd bond over that. Oh were we ever wrong. Jasmine started to get extremely needy and affectionate with us and Mila and eventually Mila snapped and started the hissing and the growling. We separated them for a couple of days, because at the same time, Jasmine appeared to react to the rabies vaccine (skin crawling, excessive rapid licking herself, and a bit of paranoia). We assumed that Mila was reacting to whatever reaction Jasmine was having.
After a couple of days again, the two got back together and curled up and we seemed to be on the road to recovery. Two days after that I came home after leaving them alone for a couple of hours and we were back to square one again with the hissing. Jasmine appears to make it worse for herself this time again because she wants attention from her sister and she's getting very close to her pushing the issue. We tried separating them again, but it didn't appear to help, so today I've been letting them go free and try to work this out for themselves.
The odd part is, they will sleep together like they used to at night, cleaning each other. Then they are fine in the morning, by the afternoon they are having issues, and then later in the evening they calm down again.
Products I've tried: Feliway diffuser, liquid catnip on the noses to confuse smells, and tons and tons of playtime to get them in the same room socializing. When they focus on the toy, the anger seems to be gone.
After a short novel, I guess my question ultimately is whether there is any other advice or guidance on why this is happening, and what we can do to help. I'm wondering if Jasmine still has a foreign smell to Mila and that's why she's reacting, and if so, what would be causing that foreign smell. If it's not a smell, and just a behavior/dominance issue (because Jasmine is being overly affectionate and needy), when do they go back to normal. There hasn't been a serious attack yet, but it's somewhat unsettling and makes us nervous seeing Mila acting out like this.
Anyhow, if you've made it this far, thanks for reading. And I appreciate any advice.
