I understand not being able to do something due to limitations like OCD. But when safety of others (in this case cats) come to place, then it's time to surrender and ask/demand help. I'd tell my therapist to come see me at my house. Or I'd show her pics. Hopefully that would get ball rolling. When you see your pdoc show him the pictures. Show the one where you have cats crawling in trash. Tell him you need help. Please. You don't need anyone's permission to get help
