<human>: I have had a cat for about 3 years now and I wanted to neuter him around the suitable time and everything but couldn't afford to and never did. So he usually sleeps in my house for hours and then roams around outside the rest of the day and night. He's a bully and will bite, his, and  fight you if you annoy him. About 6 months ago I got a small stray cat that stays outside and never leaves the yard. Well my big older cat CONSTANTLY fights my small cat. The small cat never fights back and just runs or gets cornered and takes the beating. Since there both outside I don't know how to stop my big cat from beating up my small cat. I've fussed and whipped my big cat but it does nothing.

Can you condense the text into a few key points?
<bot>: 2 outside tame cats. 1 older male fights young male cat constantly, and never provoked to do so. I'm tired of seeing the small one bullied! How can I stop this!?
