I have had my cat for 2 years. Someone gave him to me because he would have been put on the street. I learned from a vet that he was neutered and male. Recently (within the past 2 months) my cat has been showing very strange behavior. I stopped allowing him to sleep in the bed with me because he was becoming extremely territorial and would even walk in front of my face while I was sleeping. Now whenever I get home from work he masturbates around 4-6 times. I actually find it to be very disturbing and I don't know how to make him stop. He was not doing this in the past and it's always with this cat bed and blanket I gave him which was previously next to my bed but I ended up having to move into the living room because I didn't like how he would just be right there masturbating. If I'm home all day like on the weekends he will masturbate many times throughout the day. Like more than once per hour it seems. Also when I went to work today I noticed a strange smell on my pants near the crotch area like pee or spray from a cat. It was very strong idek how I didn't notice this morning. He was not doing this in the past. I thought neutered cats don't do that type of thing? I am the type of person who throws a lot of clothes on the floor but I just don't understand why he's doing all of these things now that he never did in the past. Please help
