I have two cats, they've both lived together for around 3 years and they've never had a problem before. They would play fight but nothing serious. Well last night, My cat Romeo got stuck in a small spot and couldn't get out. He started freaking out when he realized that and was going crazy in there trying to get out. Within a few seconds, my other cat Ollie popped his head around the corner to see what was going on, right where Romeo was looking. Since he was already jumpy and scared, He flipped the :idea: out. He jumped really hard and hit his back on the corner of something 2 inches above him, then hurt his feet coming back down. Romeo and Ollie started hissing and growling at each other and within a few seconds Romeo squeezed his way out and chased Ollie like he was going to kill him. We ended up catching both of them but Ollie was bleeding. We separated them for the night and after about 30 minutes Ollie calmed down, Romeo was still jumpy. This morning, they were doing fine, eating together, outside together. Then they came face to face, one going out a door one going in, and Romeo flipped out again. Again, we had to chase them both down and separate them. What can we do to make them stop fighting? Will it ever go away? I need help badly, if something doesn't happen soon, someone's going to get hurt.
