My two cats (8 months old) who are sisters just got in a huge fight after my husband yelled. They like to remove the shower drain and had dropped toy springs down there. I was digging them out with a hanger when my husband went to look and got a bad cramp in his leg. He started screaming and yelling because of the pain and the cats started fighting each other. Like full blown cat fight. I finally got them separated, but now they are freaking out and hissing when they see each other. Anyone experienced this or have any advice? Honey one of the kittens had unrecognized cat aggression towards Cinnamon after a spay, but the fighting was nothing like this.
