Hello, yesterday my two cats- both female, sisters, fixed, about 3 years old- saw another cat in the window and ended up attacking each other savagely. Until now they've been extreamly docile. I posted a question here and the advice I was given was to just keep them separated long enough and they would get over it. While I am very aprechiative of the time and effort given to answer my question it has not been fruitful. The next day I tried to bring them together and they started right where they left off. One is the runt of the litter and she now has a bloody gash across her face. Please, is there something I can actually do?
