For several days at the end of last week and the first of this week we've had lots of growling and hissing. Every time one cat rounded a corner and encountered another cat, we had noise. Sadie had stopped sleeping in our bedroom and Sassy started sleeping in our bedroom. For eighteen months Sadie has called our bedroom home. She's either in the window, on the bed or under it. All of a sudden Sassy (who has never shown any interest in our bedroom) is sleeping there every night and even on the bed once in a while. We thought perhaps there was a power struggle but after eighteen months of living together, what could have set that off? Sadie had started peeing on the floor by the front and garage doors, even once in the dining room by the sliders. We've racked our brains trying to figure out what the hell is going on. Sadie, who was getting more affectionate with us since we stopped her meds, both bit and scratched me yesterday while I was petting her. She got a claw hooked in my arm and while I was trying to disengage it, she bit me and I bled. Real blood. And Sassy has taken to pooping on the new large mat I bought to put under the two living room litter boxes. In her defense, she always uses the same corner and keeps it on the mat. Easy to clean up and she's been consistent. For a couple of months we had no problems, every one was using the litter box and all was calm. Something started them off again but we have no idea what.
I finally broke down and purchased four of the Feliway dispensers with Feliway and an extra six pack of the inserts. The literature says it could take a month to work. I installed them Wednesday morning and right now both cats are asleep. Sadie was active early this morning but Sassy has been asleep since we got up. I checked - she's breathing. Sassy has always slept more than Sadie after we discontinued Sadie's meds. Let this be a lesson to anyone reading - if you have a female cat and want another one - get a male. Two female cats that are unrelated are like two women in a kitchen, it often doesn't work out well.
