Question To Cat Lovers

Hello. I start with the fact that I have a big male cat about 4 years old, and a tiny one that is not yet a year old. At first, the big man was somehow not particularly interested in women, in the sense that the situation was tolerable. He ran away from home several times, but since he was not used to the environment, he returned quickly. Last year, however, I could barely stand it ... He walks from corner to corner, makes terrible sounds, unbearable meowing, separately marks clothes, shoes, bags that have fallen to the ground ... He marks the walls, my curtains, the bed linen ... and so you guess that I became a slave to a cat .. Cleaning, constant washing, separate smell .. I'm ashamed to let anyone in the house ... I tried some repulsive sprays, which, apart from risking your own health, are of almost no use .. And here comes the decisive moment .. that I see no other way out but castration, and I'm very sorry to somehow take away something that nature has given them .. I have almost no other options. I can't let them run outside, to relieve themselves, because that would be irresponsible. On the other hand, we currently live in a small apartment, and I have the feeling that the animal is tormented by walking around such a small area and looking for a way out. What would you advise me, are there any medications, other sedatives or a way to stop him from tagging? Have you had similar problems?
