My one cat PC was a stray my husband and I took in. He was not fixed at the time. After he got hurt, he got stitches and fixed and we kept him. Now, I have another cat that I had since he was a baby, his name is Twiggy. Well... Twig has been living with my mom for the last 3 years and we finally brought him in with us since we will be moving soon. Him and PC love to play and chase each other... Only problem is... When PC gets too excited, he tries to mount him like a female and Twiggy flips out and attacks him and then attacks me. He actually just latched on to the back of my leg like a wild animal. I closed him in the bathroom to cool off. I am not sure what I can do to keep this from happening. Neither one is hurt from what I could see. I check their eyes and ears and no major damage was done. They screamed for like 5 seconds before I yelled and broke them up. I don't want this to keep happening because they are both going to be living with us. I don't want to give up either one, I love them both so much. I can't find anything online about this. I might be searching in the wrong spots of something.
